3 and 4 string pickups are primarily made for cigar box guitars. Designed for a full tone with the ability to grit up when asked. They have a pure chime that reacts well to overdrive and fuzz.

I designed these pickups around the requirements of cigar box players. The aim was to create a pickup that would have a fantastic clean tone. As well as that it needed to have grit when used with overdrive. It needed to retain clarity and not to become total mush with heavy fuzz. The overall feel needed to have a low-fi vibe with a loose, open attack.

Cigar box guitars are becoming more popular. They’re simple construction makes them cheap and easy to make. There are a lot of people making them in their garages. Having been asked many times to make pickups for these cool instruments, here is the result.

Both the 3 and 4 string humbuckers are designed for cigar box guitars. The 4 string pickups double up as an electric steel string ukulele pickups.

The whole design phase turned out more complicated and involved than I had anticipated. I do like to deep dive into the tones my potential customers use.

After a fair bit of experimenting for these 3 and 4 String Pickups. Here is what I came up with;

3 and 4 string single coils

The 3 and 4 string single coil pickups were designed around my hot Strat pickup – The Tui. Single coil pickups have a more immediate attack, a cleaner, purer signal and great dynamics. If you need a sappier, cleaner sound the single coil is for you.

3 and 4 string humbucker

The 3 and 4 string humbuckers have windings based on a Gibson PAF. But with the ‘in coil’ rod magnets of a Fender. Humbuckers have a fuller, meatier sound with a more pronounced mid range. They are, of course, hum canceling which can be very useful especially when using overdrive.

The coil is designed around the Gibson PAF. Though scaled down for the smaller bobbins of either 3 or 4 string. I used rod magnets inside the coil to create clarity and string definition (like a Fender). All the flatwork of these pickups is laser cut in house. That way I can control every element of the design.

Why the staggered magnets on the 4 string humbucker?

Each of the 2 coils of the 4 string pickup has 4 magnets. Only 2 are visible from the top. From below you can see all of them.

The higher magnets emphasize their related string. So the bass strings have a little more bottom end. The treble strings have more twang.

These humbuckers have 4 conductor wire as standard. This makes it easy to add switches for coil tap or series/parallel broadening your tone pallet.

I am always happy to help with wiring suggestions or diagrams.

String spacing 

The string spacing on the 3 and 4 String Pickups is the same for all 4 of these pickups. – 10.4mm

I chose this spacing to be the same as fender guitars. Lots of makers use Fender spaced bridges.

The spacing is the distance between the pole magnets – center to center. Here is an article to help if you are not sure how to measure your pole spacing.

 

Design Requirements

 What is a cigar box guitar?

A cigar box guitar is just that- a guitar who’s body is made from an old cigar box. They generally have a neck transferred from another instrument or custom made.

There are many variations on the theme but that’s the basis of it.

They usually have either 3 or 4 strings. Although they are generally electrified they can also be acoustic.

Many players like to use cigar box guitars through fuzz boxes or old Amplifiers. To prevent excessive noise I have designed these pickups as humbuckers. That way the noise is kept to a minimum. Here is an explanation on how humbuckers work.

Another advantage of humbuckers is the various wiring options. The full, fat humbucker sound is wired in series. There are options where it can be wired in parallel, giving a more Fender like tone. Then there is coil tapping, simply switching one coil off (only applies to the 3 string). All this can be done with a switch. Here are a couple of wiring diagrams to help with this.

There is no standard size for cigar box guitar pickups. Most people make their own guitars. To support this I am happy to provide CAD drawings to 3D print router templates. This will ensure an exact fit. They are designed for use with a 1/4” cutter and a 3/8” guide bush.

Pickup positioning

One of the most important considerations with a pickup is where to place it along the string length. Put simply, the closer it is mounted to the bridge the more treble and twang. Closer to the neck gives more bass and a more mellow tone. It is up to you, there is no right or wrong. 

I have read articles where it was recommended to position the pickup in relation to the string harmonics. The thinking being it should be over the 24th fret harmonic. For me this doesn’t work. String harmonics are not in fixed positions, they are a proportion of the string length. As soon as you start fretting notes they move.

My advice for guitar makers is to experiment. Make a jig so you can mount the pickup from above. That way you can listen to which position sounds best for you and your instruments. There isn’t a ‘best’ place, just the best for you.

4 string story

The initial design idea for the 4 string humbucker came from a conversation with Corey Muxlow from Australia. He was making an electric ukulele for Drydon Mitchell from the band Alien Ant Farm. He wanted a pickup, we talked and the 4 string was born. I am told Drydon loved his ukulele and it’s getting regular use.

3 and 4 String Pickups Height

The base plate is designed with the intention of a pick guard mounting like in a Strat type guitar. It is also possible to mount one from a pickup ring like with Gibson humbuckers. I’ll leave it up to you to figure out what works for your instrument. There is always going to be some modifying needed to fit this pickup.

Remember, you’re aiming at a pickup height of 2mm. That’s from the top of the magnet to the underside of the string. That measurement is taken when fretting the last fret.

That measurement is not super critical but you need to be close. If the pickup is too far away you will not get a strong, clear signal.

2 String Pickup

I was contacted by a customer recently wanting a 2 string pickup. Was it for a 2 string guitar? Maybe some other instrument…

Why would you want a 2 string guitar pickup?

The idea behind this pickup is for it to be mounted to a conventional electric guitar for it to just ‘hear’ the E and A strings. Then that signal is sent out separately and put through a pedal to lower it an octave. The octave down sound can be amplified separately or combined with the signal from the 6 string pickups. It’s one of those ideas that the more you think about it the more uses you find for it.

I came across this idea before back in 2014. Here is a blog post on 2 string pickups I wrote back then. The ones I made then were a little different. One was for a bouzouki and another for an acoustic guitar. The overall idea was the same. The idea is to only hear one or two strings and to lower the signal by an octave.

Design

I had a lot of questions for the customer. In the end I concluded the pure signal from a single coil pickup was needed. And that pick guard mounted mounting would be best.

So I got on the computer and designed what was essentially a cut down Strat pickup.

My plan was to design the pickup using a CAD program and then laser cut the top and bottom plates. It is constructed the same way as a Fender.

The advantages of using a laser cutter are simply accuracy and repeatability. The customer wanted 2 pickups and, well, I have been asked before, maybe I will again. Spending time on the CAD drawing means I’ll only have to do this once. Next time it will be a lot easier.

Pickup Construction

The bobbins have a top and bottom plate laser cut from Forbon (like a Fender). They are held in place with the magnets. I have my magnets specially made for me, these are the two middle magnets from ‘Tui’ pickup. As extra security I always super glue the magnets and flatwork together as well as insulate the magnets from the windings – I want to be sure. I haven’t shown that in this picture.

I chose the Tui design and winding count because of its strong clear signal. The bass strings need to have a big clear chime if they’re going to be lowered an octave. I don’t want them to sound mushy or undefined.

Once they were wound I potted them in hot wax to prevent micro-phonic feedback. I shield these pickups using foil hidden under the cloth tape. I often get told by customers how noise free they are. The hook up wire is shielded 2 core and earth. This means the pickup phase can easily be changed. They are wound to be in phase with single coil pickups.

It’s turning out to be a really cute little 2 String Pickup.

The finished pickup

I did consider designing and 3D printing a cover for this 2 string pickup. I think it will be something I’ll do in future but there isn’t the budget for that this time. To finish the pickup off after wiring it up I taped the coil for protection. It’s ended up looking more like a mini Tele bridge pickup.

And there’s the perfect space on the bottom for one of my stickers.

A few weeks later I received an email from the customer saying – “It’s sounding great – I’m noticing much better string isolation then what I was getting with the cheap cigar box pup”.

He included this picture of his rather cool looking guitar:

If you have a project in mind please get in touch. I’m not always going to say yes but sometimes I do.

Remember, you’re aiming at a pickup height of 2mm. That’s from the top of the magnet to the underside of the string. That measurement is taken when fretting the last fret.
