Hofner Pickup – an interesting repair

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).

http://en.wikipedia.org/wiki/Emlyn_Crowther

 He wanted to know if my coil winding machine was up and running –  he had an interesting pickup for me to wind.

Early Hofner pickup

 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.

inside an old hofner

 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.

 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.

The Cool 90 is a P90 based pickup available in both Dogear and Soapbar. Designed with Jazz and Blues players in mind it produces a clear, full, well balanced tone. Never harsh, always full and musical.

The bridge pickup has an organic sound with a lower mid push ideally suited to dynamic lead lines and tight rhythm playing.

The neck pickup is clear and chiming with enough clarity to always be heard in the mix. It has that lovely woody tone especially in an archtop.

For ‘full fat’ P90 tones have a look at our “Sassy” P90 pickup set.

The Cool 90 Story

Like many of my pickups the Cool 90 started with a repair job. A customer sent be a faulty Gibson P90 out of a 1955 Les Paul Junior. Naturally, I took measurements and completely analyzed every detail of it. Unlike the information in the books (and internet) it had less windings and Alnico II magnets instead of Alnico V.

And what a great sounding pickup it was.

I decided to make my own version of it to compliment the ‘Sassy” P90 pickup I was already making. The Sassy has the classic “full fat” P90 tone, plenty of growl and cut through.

The idea behind the “Cool 90” was to make a lower powered version for the cleaner player. Still keeping the classic P90 character but with less grunt.

Larry and the Trons

Larry and the Trons is a short video by Brett Kingman to demonstrate Mr Glyn’s Pickups TheTron pickup set in a Telecaster Cabronita.

I sent him a set of TheTron pickups to make a demo and this is the 4th video he’s made – he must like them.

I designed TheTron pickup set with Gretsch guitars in mind and in particular the lightly overdriven sound of early Malcolm Young. It’s great when a player takes your design and makes you re-think it.

Since Brett fitted his set into a Telecaster Cabronita I’ve changed the spec of these pickups and now offer them in 52mm and 49.2mm spacing to match Fender style bridges. I do try and listen to players whenever I can.

TheTron pickup set is based around the legendary Gretsch pickups Of the 50’s and 60’s. To say TheTron has character is an understatement. TheTron is full and rounded with a well balanced mid range but with that distinctive ‘Clank’ that separates it from other pickups. The neck pickup is clear and fat and the bridge stands out from the mix without ever sounding harsh.

Over the years I’ve repaired a fair few old Gretsch pickups and noticed the best sounding ones are at the upper range for ohms. I’ve taken that design and tweaked it until I got the fullness I was looking for but without loosing clarity or clank.

Most of my pickups are made in collaboration with a professional player, but not TheTron. I started playing guitar at the age of 16 when I first heard Malcolm Young – a Filtertron through an almost clean valve amp. I didn’t feel I needed another set of ears for this one, I knew exactly what I wanted.

I needed this pickup set to be crystal clear with a clean amplifier but to come into its own when pushing an amp to clip. The neck pickup needed to be clear, full and chiming in both a big archtop and in the neck position of a Telecaster. The bridge pickup needed to have no shortage of character, a clean almost jangly tone when played gently but with enough go in it to push the front end of a valve amp to clip when you dig in.

TheTron is the perfect pickup as a Gretsch upgrade, for the modern player wanting something other than Gibson style humbuckers, rockabilly players after that traditional tone, jazz players or, like me, Malcolm Young fans. There’s so much you can to with The Tron.

For the modern player with one foot in the past.

Integrity humbucker demo

Integrity humbuckers. PAF Alnico 2 vintage voiced pickups

Thought I’d let you know about a new demo of my Integrity humbucker by Ben Neil. https://www.youtube.com/channel/UCVg2uivLJff7FTWmwTYVZWQ

Here’s the short, to the point version:

For those of you wanting to delve a little deeper here’s the full version:

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”.

Bellbird Strat Pickups

Bellbird vintage voiced strat pickups

A set of MrGlyn’s Bellbird Strat Pickups getting some national radio play in the hands of Jason Herbert.

The Stratocaster has been around since 1954 and the legend continues. Reading the internet (!?) tells me there have been good and bad years or decades, guitars to avoid and ones worth hundreds of thousands of dollars. I’ve been repairing guitars since 1995 so I’ve played a lot of old Strats and analysed a lot of old pickups. Vintage pickups aren’t all great but the good ones are fantastic.

I’ve based my Bellbird Strat Pickups set on the best of the old pickups I’ve had the pleasure of playing through . So I use AWG42 heavy formvar insulated wire – there’s something about the thickness of that insulation that just works with an old Strat pickup.

I’ve aimed for that old quacking chime that makes Strats wonderfully percussive but with a singing quality that’s so musical. Warm and clear with beautiful almost reverb-like clean tones – that’s what I want out of an old Strat. The neck needs to be fat, round and clear, the middle pickup needs to quack and the bridge a cut through twang without thinness. The all important ‘in between’ sounds in positions 2 and 4 must be balanced and characterful. Nothing says Strat more than these sounds.

The Bellbird set has been designed mainly for clean tones but they’re certainly not afraid to perform with a bit of gain. As part of a HSS set they’re great with one of my ‘Integrity’ humbuckers in the bridge position.

I agonised for months over names for my Strat pickup sets then during a camping trip to Tauwharanui Regional Park I heard my first Bellbird and realised that was the sound I had been looking for when I was designing this set. The comparison in tone between the Bellbird and the more common Tui seemed exactly what I had in my head when designing my Strat pickups. Bellbirds don’t just go tweet, there’s a depth and warmth in the tone. It’s so hard to describe sound and the difference between pickups but I think the difference between the Bellbird and the Tui sum up the difference between my vintage and hot Strat pickups. So I called them the Bellbird and the Tui. https://mrglynspickups.com/2020/03/29/bellbird-vintage-strat-set/

Treble Bleed, an explanation.

A brief explanation of how treble bleed circuits work and why you might need one.

With some help from Sammy the dog.

Here’s a more wordy explanation of a Treble Bleed: http://mrglyn.blogspot.com/2016/10/treble-bleed-capacitors.html

Treble bleed capacitors

You may have noticed that when you turn the volume control down on an electric guitar it not only gets quieter but also more muddy. As the volume goes down so does the clarity. This can, of course, be useful. Quite often you’ll want to be able to take some sparkle off the sound of single coil pickups. But with humbuckers I think they just get too wooly and undefined as the volume goes down.
So here’s the solution, it’s cheap and simple, easy to fit and makes humbuckers so much more versatile without taking anything away from the full volume sound. I’m talking about treble bleed capacitors.
 For our purposes all you need to know about capacitors (caps for short) is they allow treble frequencies to pass through them but block bass. The frequencies involved depend on the value of the cap.
 The volume control (potentiometer or pot) on an electric guitar looks like this:

It’s a fairly simple device, As you turn the volume down the resistance between the ‘in’ and ‘out’ leg increases. This makes it increasingly harder for the signal from your pickups to get through. Less signal means quieter.
 Here’s the same thing with our cunning treble bleed:

This one has the ‘Orange Drop’ treble bleed which has a resistor added to it. This resistor softens the treble as you turn down making the effect more subtle. My preference is for the cap on its own.
So as you turn down and the the resistance increases there’s an alternative path for the signal  – through the cap. But the cap will only let treble through. As you turn the volume down you’re also turning the bass down. As a result you have a usable single coil (ish) sound when the volume is low. If you’re overdriving an amp the result is cleaning your sound up. So with a high gain amp and your volume at about 1/4 you get a bluesy breaking up sound , crank the volume on the guitar and you’re rocking.
Here’s a picture of me rocking.

 As you can see, it’s very effective.
On my guitars I prefer a simple treble bleed (0.001uf), no coil taps or series parallel. Just the volume control.

Testimonials

I put the integrity pick ups into my Jim Root Jazzmaster last week.
I gigged with the guitar on Sat night and am so happy.
They have the versatility that I’m looking for.
Thanks

Bought a set of Mr Glyn’s Integrity humbuckers and they are awesome! These pickups do everything from clean to blues rock to screaming distorted rock tones. So great to just roll off the volume, have it clean up but still stay loud and defined. My guitar is now super versatile and sounds great! Thanks
