The season is changing, old guitars are coming out of cupboards, if your electrics are crackly or your guitar keeps cutting out it might just be a Dirty Jack – don’t blame your pickups. It’s pretty simple really, if you’ve got a crackly guitar the jack may just need cleaning. Don’t blame your pickups straight away, jack sockets, switches and pots are more likely to cause problems than your pickups.
Of course, when you eliminate all the other possibilities you might be needing me:
Incidentally, it’s an “output” jack, not an “input” jack – just a pet hate of mine.
You can see the jack in this Les Paul is looking a tad fluffy. This one isn’t very bad but it’s worth a clean anyway as part of a set up.
I use 600 grade wet’n’dry paper used dry.
I simply tear a piece off, roll it up and clean the jack out with it. A squirt with some contact cleaner can help. It’s good to keep a piece in your guitar case in case your jack goes crackly at a gig.
You can see a fair bit of dirt can come off even this relatively clean jack. Just think what that was doing to your earth connection.
If a jack is really bad and you are gigging just replace it. It doesn’t cost much and it’s something you just can’t do without. If your jack stuffs up on stage it’s not a good look. I always have a small piece of 600 grade in my gig bag just in case. Cheers Glyn
I came across a blog I wrote in 2010 about a repair on an old Hofner pickup, thought you might be interested:
I had a visit from Paul Crowther the other day (always a pleasure to see him). He’s rather a legend for amongst other things his ‘Hotcake’ overdrive pedals and the ‘Prunes and Custard’ (my favorite for theremin).
He wanted to know if my coil winding machine was up and running – he had an interesting pickup for me to wind.
Its an old Hofner pickup which I guess is from the 50’s. The guitar has 3 of them and this one has a break in the windings so needs to be re-wound. This would normally be a straight forward job except for the design of this pickup.
This is the inside of it. The windings (around the outside) are not wrapped around a bobbin. They are just sitting in the pickup and have been wrapped in tape to protect them. In the middle you can see the magnets sitting in a hard putty. There are incidentally only 5 magnets. So the problem Paul left me with was how to wrap about 5000 turns of extremely thin wire into a coil and therefore make a pickup. After a long brainstorming session with Sheena we came up with a plan.
Very tricky re-wind
We figured that the wire had to be wound around a bobbin and then somehow the bobbin removed.
So I made this bobbin. The sides are plastic from a Strat pickguard (white) and the centre has been carved from candle wax.
The bobbin bolts together and is attached to another plastic plate which in turn fits to the winding machine. The idea is to wind the pickup on this and then warm the completed coil up and melt the wax. The wax should seep into the coil thus potting it as well. Then the sides can be unbolted and voila a copy of the original coil.
Winding the coil wasn’t any different from any other pickup – so now for the tricky bit.
I warm the coil ever so gently with a heat gun. I put my free hand next to the work to judge the temperature – if it gets too hot the plastic will melt and I’ll be starting again.
When I see some wax oozing out I ever so gently remove the top plate.
With the wax exposed I can apply more heat and watch it flow into the coil and as it cools becomes solid.
Then I wrap tape around it to hold everything in place. I cannot emphasize enough how fiddly this is. There are a few stray wires and if any of them break I’m starting again.
It may not be much to look at but its taken hours. The slight curve is to match the shape of the pickup casing. I’ve tested it and I’m pleased with it at 5.5Kohms. In the background you can see the magnetic lugs – I had to dig them out of the putty.
I put the whole thing back together using ‘friendly plastic’ instead of putty then fill the casing with wax, solder the back on and its finished.
Its been quite a task but I’m happy with the result.

I like to support my customers as much as I can so here is my drawing of Gibson Modern Wiring – Les Paul.
The modern wiring is used in most Les Pauls and it’s great for players wanting to roll off some treble when the guitar volume is turned down.
The difference between the modern and 50’s wiring is in how the tone capacitor is connected to the volume pot. It’s a very simple modification if you have 50’s wiring and are curious.
Modern Wiring – Les Paul
I’ve linked below to my 50’s wiring diagram so you can see the difference.
Another thing to remember is that you can actually use both wiring methods on the same guitar. It is possible, for instance, to use 50’s wiring for the neck pickup and modern for the bridge. That way the neck pickup would retain some clarity as you lower the volume. The bridge pickup (with the modern wiring) would loose a bit of high end with the volume down a bit and therefor smoothing off the treble. It just depends on what you’re trying to get out of your Les Paul. Then there’s capacitor choice, pot value, coiltap or series/parallel, or even out of phase – the list goes on. I will be writing more blogs to cover all that at some point.
It’s always important to remember that here is no right or wrong, despite what you may read on social media. It’s all just a matter of personal taste. These wiring differences are all subtle too, the place to start is with great pickups.
Mr Glyn’s “Jazz Bass” pickups are inspired by the Fender Jazz pickups from the early 60’s. Low powered vintage tones suited to players looking for a clean, clear, springy tone. Positive, percussive bass response, woody mids and clear highs. Designed for players wanting a pure tone with either fingers or a pick.
All my Jazz pickup sets are RWRP so they are hum cancelling when both pickups are on.
I love Jazz basses, that off-set body looks so cool and the narrow neck makes it very easy to get around. Looks, play-ability and versatility make it hard to beat.
The J bass has such a classic tone. The sound of a Jazz with both pickups on can be heard on so many recordings, it’s so distinctive. It’s the sound of two coils connected in parallel, like a Strat in positions 2 or 4. It’s that clear, scooped tone. The pair of coils in a Precision Bass are wired in series which gives it a bigger, more powerful sound with a lot more lower mids but the clarity of a J Bass can really stand out.
Over the years I’ve re-wound a lot of old Fender pickups. I like to make notes to record what I find in these old pickups, wire gauge, insulation types, d.c. resistance, magnetic gauss, dimensions. My notebook is getting pretty full. This is my constant reference when I’m designing a new pickup, that and my ears.
I’ve based these pickups on the best of the old Fenders I’ve come across over the years. Not all vintage pickups are great but when you see enough of the good ones patterns begin to form.
I still repair pickups and still add to my old notebook, always learning 😎.
Here’s some info on the Integrity humbucker set and you can go to my Integrity page for lots more demos:
Inspired by the early Gibson PAF pickups the Integrity-vintage humbucker give the classic full, balanced tone we all love. Asymmetric coils give an open sounding mid range and the Alnico II magnet gives clarity and balance. A rich bottom end, characterful mids and sweet treble make this a pickup set for every situation – Jazz, Blues, Rock, it does it all.
Every pickup manufacturer makes a “Vintage” humbucker based on the Gibson PAF, of course they do – old Gibsons sound so good.
So how come they all sound so different? Well, the simple answer is that PAF’s were all different. I’ve been a full time luthier since 1995, whenever I come across an old humbucker I test the ohms and the gause and have a good listen. They’re all different. My conclusion is that pickup manufacturers have taken the PAF they like and based their own version on that. Old PAF’s vary so much so modern ones do as well.
I like my own version to be clear sounding, have obvious string separation and definition and to keep clarity no matter how much gain. The mids must be strong and woody, this is not a “scooped” pickup. The clean sound needs to be chimey and clear with no mush; through a valve amp I want clarity. When I tickle it I want clean and vocal sounding when it clips. The bridge pickup needs to be well behaved with high gain and clear with enough cut through so the drummer knows you’re there. The neck smooth, clear and articulate. Warm but with none of the boom you get with a more powerful pickup.
I don’t want much do I?
My “Integrity”-vintage humbucker has an Alnico II magnet and I’ve used plain enamel insulated magnet wire with asymmetric coils to open up the mids. The very first pickup I ever made back in 1995 was a PAF style and I’ve been tweaking the recipe ever since. Like all my pickups I’ve used a number of test pilot players in its development as well as gigging it myself. It wasn’t until around 2015 that I settled on this particular design. I did a gig with a set in a PRS SE series only last weekend – sounded great to me.
The full and honest sound of the Integrity-vintage humbucker along with it’s timeless tone inspired the name “Integrity”.

It’s always interesting to see where my pickups end up, in this case Hamurana Guitars NZ.
Hamurana Guitars
They make World class guitars combining looks, playability and tone. I’ve played a few – they are outstanding.
Hamurana have used my pickups in a few builds and it’s always great to see what he comes up with. This time he’s used a pair of my my Black Sand humbucker size P90’s.
You can get in touch with Hamurana Guitars and order your dream guitar here:
The humbucker sized P90 is a great pickup – it sits tonally between a humbucker and and a strat type pickup. If your neck humbucker is a bit thick and woolly sounding for you, you want more clarity, or just want a different tone, then this one may be the answer. The physical size of this pickup is identical to that of a “normal” humbucker so it will pop straight in.
P90’s are different to other single coil pickups. They have a wide, flat coil similar to that of a Jazzmaster but the magnetic field is a very different shape. Fender single coil pickups have the coil wound around the magnet giving a focused, precise percussive sound. A P90 has 2 bar magnets underneath the coil; this broadens the magnetic window allowing the pickup to listen to a bit more string and thickens the sound. I chose Alnico V bar magnets for this model to help give some grit and power characteristic of a P90.
Of course, too much power and the pickup would sound too thick and bass heavy which is not its purpose. Too little power and it just won’t snarl.
Humbucker sized P90s are such a useful pickup. They sit tonally between a single coil and a humbucker (roughly speaking). and their physical size means they pop straight into any humbucker equipped guitar.
The development of my “Black Sand” pickup was a bit backwards. Usually I make a bridge pickup first and work from there but with this one the neck pickup came first. I had a customer ask for a neck pickup for an es335 to sound clearer than his existing Gibson humbucker. I sold a few neck pickups before thinking it would be a good idea to have a set. So I started work on the bridge pickup.
I wanted this bridge pickup to have clarity in the lower mids to stand out from humbuckers while having enough power to grit up nicely. I wanted it to be clean when tickled and to growl at you when you dig in. P90’s are all about dynamics. It had to match the existing neck pickup or work well as a stand alone in a HSS situation.
Of all the pickups in my range this one came together the quickest. There were only 4 or 5 prototypes and I was happy. Experience and intuition combined with a notebook where I’ve written down details of every experimental pickup I’ve made since 1995.
There were a load of prototypes in and out of a Les Paul, Tele Delux and PRS, through different amps and in the hands of different players. I never trust just my own ears with my pickups. I like to get opinions and suggestions from a few players before making any final decisions. I listen to what players say and I adjust prototypes accordingly, but at the end of the day the final decision is mine. I’m always aware of the phrase “a camel is a horse designed by committee”.
It took a while to get this one right. A pickup would sound great at workshop volume, them I’d play it in a band situation and it would be too boomy, too much like a humbucker. So I’d have a think and make another. In the end persistence paid off.
The pickups I finally settled on went into my Les Paul and off to a gig for the ultimate test, and that’s where they’re staying.
The neck “Black Sand” is a great match for either my “Integrity” or “Cloud Nine” bridge humbuckers or as a set with its equivalent “Black Sand” bridge humbucker sized P90.
I agonised over what to call this pickup set. I wanted a name that would reflect the apparent contradiction in P90’s. From the perspective of a humbucker player they are clear and chiming. From the viewpoint of a single coil player they are powerful and gritty. They’re one thing while looking like another. I wanted a oxymoron to reflect this contradiction, one that might include the unique magnetic structure that gives the P90 its character. So I went for a run along Muriwai beach to think. And there it was staring me in the face (literally). Muriwai has black volcanic sand due to its iron content and it’s magnetic. So I’ve called this set “Black Sand”.
I’m very happy with this pickup – hopefully you will be too.
The ‘Mini’ is inspired by the Gibson mini humbuckers of the 70’s used in the Les Paul Deluxe.
The ‘Mini’ is a clean clear sounding mini humbucker with the warmth and clarity from an alnico II magnet combined with low winding strength. This gives them a full, smooth, chiming bass, clear mids and an almost jangly treble, present but never harsh.
Great for jazz, funk, blues, pop or any genre that requires a clean, low powered humbucker set.
Mini humbuckers are great pickups, lower in power than their full size sisters their clarity comes from less windings around a smaller bobbin. The smaller size of the pickup means they ‘hear’ less of the string length than a full size humbucker. The result is a clearer tone with less of the lower mid range push that you get from a PAF.
The neck pickup has a clear voice ideal for funk or jazz. The neck and bridge pickups together have a perfect balance when used together, ideal for clean rhythm playing. The bridge pickup alone has a cheeky ‘cut through’ quality pushing you to the front of any mix.
Although he Les Paul Deluxe was a short lived guitar in the Gibson range the mini humbucker has lived on. It is a very popular pickup in custom guitars particularly the neck pickup and is a great match for Mr Glyn’s ‘Cruel Mistress’ telecaster bridge pickup.
If you’re looking for a pickup that is clearer than a PAF, has a less prominent lower mid spike with an even balanced tone then the mini humbucker could be the pickup for you.
Been having some fun making a pickup demo using a skateboard lap steel.
The Mr Glyn’s “Sassy” P90 is a pickup set influenced by the Gibson P90’s of the late 50’s. The “Sassy” have a distinctive woody aggressive tone, full of character. The highs are smooth yet punchy, there’s a chiming bottom end and a very obvious mid range that pushes through the mix. If you tickle the strings they’re clean and clear but dig in and there’s no shortage of power to drive the front end of your amp.
I’ve grown to love P90’s over the years, it’s the sound of those early Gibson Les Paul Juniors. It’s a pickup that needs no extras, just straight into a good amp. They’re happy to power pedals but there’s a fullness and balance that seems to need nothing else.
I wanted the “Sassy” P90 set to live up to its name and have the dynamic range that I love about P90’s. The wide flat coil of a P90 gives a richer, less percussive tone than other single coil pickups and this is where the full tone comes from. I’ve sat both neck and bridge pickups on top of a pair of Alnico V magnets to give the power this pickup needs and help add that bit of grit when played hard.
I’ve made the neck pickup smooth and fat but with clarity and chime enough for jazz. The bridge pickup has the dynamics, pushy mids and aggressive highs when pushed but cleans up when you ask it to.
This is a pickup set that would be happy in almost any situation, blues, rock, punk, reggae… If it’s a full bodied, dynamic P90 you’re after look no further.
I’ve named this set the “Sassy” P90 set to reflect these pickup’s attitude, they’re bold, spicy, disrespectful and a bit cheeky. https://www.youtube.com/watch?v=iJtZkIbaCZU
Take a Squire Affinity, give it to luthier Ramsay Phillips, add some Mr Glyn’s pickups Clear View humbucker set and see what you get? Superb demo from Jason Herbert – all 3 of him.
The “Clear View” humbucker is something different. It’s a humbucker for players that don’t like humbuckers.
This pickup set is all about pure clarity. There are no pushy lower mids that make your clean sound a mush. The highs are clean and clear but not harsh, the bottom end is clear but with none of that humbucker woof.
If single coils are too harsh and unforgiving, conventional humbuckers too powerful and muddy then here’s the solution. The “Clear View” humbucker is low powered and balanced, designed for the textural player, great with reverbs and modulation, sits its the mix without getting in the way.
If you want a low powered ‘Vintage’ humbucker with all the character of a PAF get a MrGlyn’s ‘Integrity’ humbucker. If humbuckers sound too thick and you crave extra clarity then the ‘Clear View’ is for you.
It started with a phone call from luthier Ramsay Phillips.
I’ve got huge respect for Ramsay, he’s worked all over the world and has a great client list (including Steve Vai). He knows guitars, knows tone and he’s a thinker. So when he calls to talk about a new pickup idea I listen.
He was interested in having a humbucker for people that didn’t like humbuckers (his phrase). A pickup with clear tone and low powered but not like a PAF, clearer than that. He wanted a midrange more like a single coil than a traditional humbucker. At first I thought my ‘Black Sand’ humbucker size P90 would suit him but as he talked I realised he didn’t want the grit of a P90. He’s very well practiced at describing sound so I felt I understood what he meant. He assured me he had customers asking about such a pickup.
He wasn’t in a rush which meant I could have a good ponder over what he’d said before making anything.
Then one morning about a week later I was out on the beach with the dogs. There was quite a big swell (the sea is never calm at Muriwai) and I was listening to the sea. I was trying to figure out which frequencies in that sound I would need to remove to make Ramsay’s pickup. By the time I got home there was a plan.
I made a set of pickups, sent them to him and a few days later he called to say they were spot on. It isn’t usually that easy.
I repair quite a few old pickups and thought you might be interested this ‘68 Telecaster bridge pickup repair.
’68 Tele Bridge Pickup
As you can see it’s looking pretty tired. I quite like seeing pickups like this – it’s clearly given great service for decades. This is just wear and tear and the sign of a happy life, and although it isn’t working now there’s no reason why it can’t be made good for a few more decades.
One of the first things I noticed is the black tape. Underneath it is the original waxed protective string. I’m not sure why someone added that.
The plate underneath has aged fantastically but as you can see the earth wire is missing from it. I re-solder the connections just in case there is a dry joint but the pickup is still dead.
I suspect this is the fault- the top plate has warped over time and the corrosion has got in and damaged the windings. That top plate looks like a skateboard deck – it should be flat! This ’68 telecaster bridge pickup is going to need a re-wind.
With the back plate off you can clearly see the date.
And here it is, this is the problem. With the windings cut away you can clearly see that the corrosion on the pole piece has spread into the winding. There’s a bit of wax in there too from when it was potted originally.
So here’s the plan. I need to flatten that top plate back. Then clean up the pole pieces. I need to do something about the corrosion. And finally re-wind the pickup to original spec. And most importantly make it look like nothing ever happened.
Cleaning the poles is easy, then I flatten the top plate and glue it in place with super glue. Originally it was just a push fit. Then I treat the rust with some anti rust stuff. Here you can see it masked off so I can give the poles a couple of coats of lacquer.
Next I wrap the poles with thin tape. I want to protect the windings from future corrosion. I want this pickup to play hard for another 50 years.
Then it’s re-winding and wax potting and finally replacing the original string.
Of course, I forget to take a photo of it with the string on.
If you want a Telecaster pickup set similar to an old ’68 take a look at my “Silver Lady” set. The Silver Lady is wound to very similar spec to the old Fenders.

A big thanks to Jonathan Ho for this great New Cruel Mistress Tele Demo showing us Tele’s are for more than just country.
Mr Glyns Cruel Mistress hot Telecaster Pickups are designed for the Tele player who wants more than the traditional country twang. They have a full bottom end, cut through mids and a top end that is strong but never harsh. They’ll push you amp that bit harder without loosing that Telecaster character.
There is nothing like the high end snarl of a good Tele bridge pickup. However, Tele Pickups are complicated. It’s a sound that needs to be just right – too much treble and it can sound grating and obnoxious, too little and it just isn’t a Tele. The treble needs warmth while still cutting through a mix like a zombie banjo.
I wanted to make a pickup with a bit more power to drive an amp harder while keeping the Tele character. My biggest concern was not losing what a Tele is all about. In my repair work I come across quite a few replacement Tele pickups that just don’t sound like Teles. Bridge pickups need grit and the neck a chimey clarity and together they should be full and open and matched well enough to create almost a reverb sound with the switch in the middle position.
The “Cruel Mistress” -hot Tele uses AlnicoV magnets to help with the attack and AWG43 wire to help with the snarl.
The neck pickup on a Tele needs to be smooth and warm and have a great balance with the bridge pickup so that the middle position rings with an almost reverb-like tone. The difficulty with Telecaster neck pickups is there just isn’t much space under that cover. As a result it can be a hard pickup to get right and there were a lot of experiments and disappointments on the way. Eventually I came on a design that has enough bottom end to sound full but not so much to sound boomy. And the final pickup was a great match to the bridge.
I had help from the ears of a couple of my regular customers who were generous enough to let me load their guitars with prototypes. The whole process takes time and only after many road tests and versions did I fix on a design. As a result, each of my designs have been developed over many years of subtle changes and road tests. Having help like this means my pickups are trialed through many different amps and playing styles. The neck/bridge balance as well as dynamics/compression need to be tested in as many situations as possible to find a pickup that will work for most players.
The Gretsch FilterTron is something rather special. Originally designed in 1954/5 by Ray Butts for guitarist Chet Atkins who wasn’t satisfied by the DynaSonic pickup he was using. It has become a classic but often misunderstood pickup.
It has left a distinct mark on the sound of Rock’n’Roll. It’s the sound of Malcolm Young, Brian Setzer, Billy Duffy and plenty more. That unmistakable ‘Clank’ on the attack of the note is the essence of the FilterTron.
I started playing guitar because of the sound of A FilterTron. Listen to Malcolm Young on the intro to “Jailbreak” – that’s what I’m talking about. https://www.youtube.com/watch?v=HRo2m6RYJpI
But you don’t only find FilterTrons in Gretches, there’s the rather cool Fender Cabronita Telecaster.
So how does it make that distinctive sound? What makes it so different from a PAF?
Here’s a vintage Gretsch FilterTron from 1961, let’s take a look under the hood.
With the cover off it looks quite different from a PAF. There are 2 rows of adjustable poles and they’re bigger than on a Gibson. The top of the bobbins are rather neatly hidden by a thin plate.
Here’s where it gets really interesting. Those are very narrow bobbins and this one measures only 4.2KOhms. Not a lot of coil strength there but look what they’re sitting on. That is one fat magnet. It’s an Alnico V and literally twice the thickness of the Alnico 2 (usually) that you’d find in a PAF. So not only more powerful magnetic material but double the amount of it compared to a Gibson.
So that FilterTron sound consists of a weaker, thin sounding coil so lots of highs and twang from the windings and getting the aggression, attack and ‘clank’ from the powerful magnet.
This is the original FilterTron, the design didn’t change much through to the late 60’s although there are plenty of inconsistencies. They can have a dc resistance from 4KOhms up to 5KOhms.
By the 1970’s they had changed the design and really they just didn’t sound like Gretsch’s any more.
A lot of the modern ones are simply small humbuckers with cool looking covers and just miss the whole point of the FilterTron sound.
It’s all about those weak coils and that monster magnet.

The Clear View humbucker Story
It started with a phone call from luthier Ramsay Phillips.
I’ve got huge respect for Ramsay, he’s worked all over the world and has a great client list (including Steve Vai). He knows guitars, knows tone and he’s a thinker. So when he calls to talk about a new pickup idea I listen.
He was interested in having a humbucker for people that didn’t like humbuckers (his phrase). A pickup with clear tone and low powered but not like a PAF, clearer than that. He wanted a midrange more like a single coil than a traditional humbucker. At first I thought my ‘Black Sand’ humbucker size P90 would suit him but as he talked I realised he didn’t want the grit of a P90. He’s very well practised at describing sound so I felt I understood what he meant. He assured me he had customers asking about such a pickup.
He wasn’t in a rush which meant I could have a good ponder over what he’d said before making anything. It’s often best just to let a project sit rather than wade in and make a load of prototypes that don’t quite do it. Thinking time is important.
Then one morning about a week later I was out on the beach with the dogs. There was quite a big swell (the sea is never calm at Muriwai) and I was listening to the sea. When there’s a big swell the sea produced the full range of frequencies, it is pretty much pink noise. I was trying to figure out which frequencies in that sound I would need to remove to make Ramsay’s pickup. I often ponder problems this way and for me it often works. By the time I got home there was a plan.
I made a set of pickups, sent them to him and a few days later he called to say they were spot on. It isn’t usually that easy.
And the Clear View humbucker set was born.
Clear View humbucker
Here are some cover options for the Clear View humbucker set.
This Yamaha SA30 pickup came to me for repair the other day and I decided to take some photos and share my thoughts on it with you.
The Yamaha SA30 is becoming a bit of a legend and getting rather sought after. Gone are the days you could pick one up cheap – the word is out. Thank you internet 🥴.
This pickup was sent to me with an intermittent fault. It would work if you tapped it but stop a minute later. That pointed towards it being an internal wiring fault rather than a broken coil, I needed to investigate.
With the cover off you can see the hook up wires – these were my number one suspects. Sure enough, there was a dry joint where one of them was soldered to the connectors on the base plate. Just to make sure I re- soldered all the joints and the pickup is fixed.
But that’s not the interesting part – look at those bobbins. They’re different sizes. They each measure in the 4.5 K Ohms range but they’re clearly wound with different gauge wire on each coil. These pickups are renowned for their clarity – so what’s going on?
The smaller coil on the left must be wound with thinner gauge wire and less of it than the one on the right. Thinner wire have a greater resistance for the same length.
The coil on the right looks like a conventional humbucker coil like an overwound PAF but the coil on the left would have a less full sound. It will have less bottom and lower mids and a lot less power. But that’s just the windings.
Turn the pickup over and you can see a ceramic bar magnet but it’s how it connects to the poles that’s interesting. The bigger coil has a larger piece of steel coupling the poles to the magnet than the smaller coil. Measuring the strength of the magnetic field on the top of the poles the smaller coil is about 20% weaker. So this again gives the big coil an overwound PAF sound and the smaller coil still thinner.
So with the Yamaha SA30 pickup they’ve created that clarity by having one coil doing most of the work – 4.5k Ohms with a ceramic magnet has a bit more grunt than one half of a PAF. But the other coil on it’s own would have more of a weedy gold foil type sound. Then they’ve been combined in series as a humbucker. Smart stuff eh!

Mr Glyns Cruel Mistress hot Telecaster Pickups are designed for the Tele player who wants more than the traditional country twang. They have a full bottom end, cut through mids and a top end that is strong but never harsh. They’ll push you amp that bit harder without losing that Telecaster character.
There is nothing like the high end snarl of a good Tele bridge pickup. However, Tele Pickups are complicated. It’s a sound that needs to be just right – too much treble and it can sound grating and obnoxious, too little and it just isn’t a Tele. The treble needs warmth while still cutting through a mix like a zombie banjo.
With the “Cruel Mistress” -hot Tele wanted to make a pickup with a bit more power to drive an amp harder while keeping the Tele character. My biggest concern was not losing what a Tele is all about. In my repair work I come across quite a few replacement Tele pickups that just don’t sound like Teles. Bridge pickups need grit and the neck a chimey clarity and together they should be full and open and matched well enough to create almost a reverb sound with the switch in the middle position.
The “Cruel Mistress” -hot Tele uses AlnicoV magnets to help with the attack and AWG43 wire to help with the snarl.
The neck pickup on a Tele needs to be smooth and warm and have a great balance with the bridge pickup so that the middle position rings with an almost reverb-like tone. The difficulty with Telecaster neck pickups is there just isn’t much space under that cover. As a result it can be a hard pickup to get right and there were a lot of experiments and disappointments on the way. Eventually I came on a design that has enough bottom end to sound full but not so much to sound boomy. And the final pickup was a great match to the bridge.
I had help from the ears of a couple of my regular customers who were generous enough to let me load their guitars with prototypes. The whole process takes time and only after many road tests and versions did I fix on a design. As a result, each of my designs have been developed over many years of subtle changes and road tests. Having help like this means my pickups are trialed through many different amps and playing styles. The neck/bridge balance as well as dynamics/compression need to be tested in as many situations as possible to find a pickup that will work for most players.
So if you need some grit and aggression from your Tele this is the set for you.
A big thanks to Brett Kingman in Aussie for his demo of Mr Glyns “Black Sand” humbucker size P90. I love his relaxed approach while giving us a thorough listen to what these pickups can do.
Mr Glyns Pickups
The humbucker sized P90 is a great pickup – it sits tonally between a humbucker and and a strat type pickup. If your neck humbucker is a bit thick and woolly sounding for you, you want more clarity, or just want a different tone, then this one may be the answer. The physical size of this pickup is identical to that of a “normal” humbucker so it will pop straight in.
P90’s are different to other single coil pickups. They have a wide, flat coil similar to that of a Jazzmaster but the magnetic field is a very different shape. Fender single coil pickups have the coil wound around the magnet giving a focused, precise percussive sound. A P90 has 2 bar magnets underneath the coil; this broadens the magnetic window allowing the pickup to listen to a bit more string and thickens the sound. I chose Alnico V bar magnets for this model to help give some grit and power characteristic of a P90.
Of course, too much power and the pickup would sound too thick and bass heavy which is not its purpose. Too little power and it just won’t snarl.
Humbucker sized P90s are such a useful pickup. They sit tonally between a single coil and a humbucker (roughly speaking). and their physical size means they pop straight into any humbucker equipped guitar.
The development of my “Black Sand” pickup was a bit backwards. Usually I make a bridge pickup first and work from there but with this one the neck pickup came first. I had a customer ask for a neck pickup for an es335 to sound clearer than his existing Gibson humbucker. I sold a few neck pickups before thinking it would be a good idea to have a set. So I started work on the bridge pickup.
I wanted this bridge pickup to have clarity in the lower mids to stand out from humbuckers while having enough power to grit up nicely. I wanted it to be clean when tickled and to growl at you when you dig in. P90’s are all about dynamics. It had to match the existing neck pickup or work well as a stand alone in a HSS situation.
Of all the pickups in my range this one came together the quickest. There were only 4 or 5 prototypes and I was happy. Experience and intuition combined with a notebook where I’ve written down details of every experimental pickup I’ve made since 1995.
There were a load of prototypes in and out of a Les Paul, Tele Delux and PRS, through different amps and in the hands of different players. I never trust just my own ears with my pickups. I like to get opinions and suggestions from a few players before making any final decisions. I listen to what players say and I adjust prototypes accordingly, but at the end of the day the final decision is mine. I’m always aware of the phrase “a camel is a horse designed by committee”.
It took a while to get this one right. A pickup would sound great at workshop volume, them I’d play it in a band situation and it would be too boomy, too much like a humbucker. So I’d have a think and make another. In the end persistence paid off.
The pickups I finally settled on went into my Les Paul and off to a gig for the ultimate test, and that’s where they’re staying.
The neck “Black Sand” is a great match for either my “Integrity” or “Cloud Nine” bridge humbuckers or as a set with its equivalent “Black Sand” bridge humbucker sized P90.
I agonised over what to call this pickup set. I wanted a name that would reflect the apparent contradiction in P90’s. From the perspective of a humbucker player they are clear and chiming. From the viewpoint of a single coil player they are powerful and gritty. They’re one thing while looking like another. I wanted a oxymoron to reflect this contradiction, one that might include the unique magnetic structure that gives the P90 its character. So I went for a run along Muriwai beach to think. And there it was staring me in the face (literally). Muriwai has black volcanic sand due to its iron content and it’s magnetic. So I’ve called this set “Black Sand”.
I’m very happy with this pickup – hopefully you will be too.

The Mr Glyn’s “Sassy” P90 is a pickup set influenced by the Gibson P90’s of the late 50’s. The “Sassy” have a distinctive woody aggressive tone, full of character. The highs are smooth yet punchy, there’s a chiming bottom end and a very obvious mid range that pushes through the mix. If you tickle the strings they’re clean and clear but dig in and there’s no shortage of power to drive the front end of your amp.
I’ve grown to love P90’s over the years, it’s the sound of those early Gibson Les Paul Juniors. It’s a pickup that needs no extras, just straight into a good amp. They’re happy to power pedals but there’s a fullness and balance that seems to need nothing else.
I wanted the “Sassy” P90 set to live up to its name and have the dynamic range that I love about P90’s. The wide flat coil of a P90 gives a richer, less percussive tone than other single coil pickups and this is where the full tone comes from. I’ve sat both neck and bridge pickups on top of a pair of Alnico V magnets to give the power this pickup needs and help add that bit of grit when played hard.
I’ve made the neck pickup smooth and fat but with clarity and chime enough for jazz. The bridge pickup has the dynamics, pushy mids and aggressive highs when pushed but cleans up when you ask it to.
This is a pickup set that would be happy in almost any situation, blues, rock, punk, reggae… If it’s a full bodied, dynamic P90 you’re after look no further.
The Sassy is available in Dogear and Soapbar.
I’ve named this set the “Sassy” P90 set to reflect these pickup’s attitude, they’re bold, spicy, disrespectful and a bit cheeky. https://mrglynspickups.com/
So How do Humbuckers Work? By a clever quirk of physics humbuckers manage to cancel out the hum they pick up. So how do they do it? Here’s a simple explanation with some help from Sammy the dog. https://mrglynspickups.com/
A mid to hot, pickup made specifically for blues/rock players who want to push the front end of their amps. Plenty of grunt, plenty of mids and enough cut through for you to stand out in the mix. https://mrglynspickups.com/2020/03/29/cloud-nine-hot-humbucker/
I’ve been repairing a few pickups recently and I thought I’d share this one with you. It’s a Fender Lead I Pickup that was sent to me by guitar repairer Jeff Baker from Oamaru.
The Fender Lead I was one of those obscure models that never really caught on and the pickup reflects that. It’s a little unusual and that’s what makes it interesting.
It even looks different with those square topped bobbins.
Not only is it unusual looking from the top but turn it over and it shows what it’s really all about. Those are 12 big adjustable poles screwed into substantial steel blocks and coupled to a powerful ceramic magnet.
This is clearly not a typical Fender pickup, this was designed to ROCK.
So what were Fender thinking? Well, this was 1979, the DiMarzio Super Distortion had been around for 5 years and was becoming very successful. Fender had nothing to compete with it. Looking at the spec of the Lead I pickup it is remarkably similar to the Super Distortion. Fender were making a Superstrat and it wasn’t even the 80’s yet.
Back to the repair – it came to me because it wasn’t working and typical for faulty humbuckers one coil was showing ‘open circuit’ on the test meter. In these cases I can use the good coil as a reference to what the faulty coil should be. It had a dc resistance of 7.61 KOhms. Wiki told me the final dc resistance of the whole pickup is approx. 13KOhms so that gave me a pretty good indication of how I should wind it. That’s a powerful set of coils to go with that magnet.
A bit of maths, plenty of experience and some intuition and I had a plan for winding it. Detailed information just isn’t available for this kind of job.
I stripped the bobbin and wound the coil.
I potted it very lightly because these bobbins are made of butyrate that has a lower melting point than most modern ABS bobbins – I didn’t want it to deform with the heat, I wasn’t going to be able to get another bobbin.
Here you can see the chunky pole pieces, they’ll guide a fair bit of that ceramic magnet’s strength up to the strings.
If you have a faulty pickup or are interested in my range of handmade pickups have a look at the website.
I had this Fender Telecaster bridge pickup repair in the other day and thought I’d show you it. It’s from an ’87/8 Fender Telecaster USA Standard.
Tele bridge pickups are the essence of Rock’n’Roll. For those of us that love our Teles there’s just nothing like it. So how come they sound so different from Strat bridge pickups? The magnets are usually the same, the windings are about the same so what makes Telecasters so distinctive?
There are 2 factors:
1) The Tele has a steel baseplate. This base plate increases the pickup’s inductance (by about 7%) giving it a bit more power. It also changes the shape of the magnetic field a little, broadening the magnetic window so the pickup ‘hears’ a bit more of the string. I use this principle on my ‘Tui’ Strat pickups. https://mrglynspickups.com/2020/03/29/tui-hot-strat-set/
2)The pickup is mounted to the steel bridge plate. Put a Tele bridge pickup in a Strat and you’re only half way to a true Tele sound. It really does make a big difference.
So, back to the repair – this pickup was completely dead showing ‘open circuit’ on the test meter. As with every one of these repair jobs I start by checking for dry solder joints – always worth ago. The solder joints were fine so time to look further.
As you can see from the picture there’s a lot of corrosion on the pole pieces. My suspicion is the corrosion has spread to the inside of the pickup and caused a break in the windings. I need to get in there and investigate.
