Pre-Wired Guitar wiring harness | 50s style Les Paul Coil Split Push/Pull Tones kit | Right Handed
For such a simple configuration, I must admit that the Les Paul harness has been the model I've researched and refined the most in my time making harnesses. I wanted to be respectful of the traditional aspects of the guitar that so many people love, bringing the best out of the iconic Gibson design.
I have had so many requests for Coil Split 'push/pull' LP harnesses, and have decided to make this a standard model in the harness range. But please note some of the details in the installing section to ensure your pickups are suitable and are confident in soldering the slightly more complicated install.
*Please note that this schematic only works for coil split function and I don't offer custom harnesses.
Important note - This schematic/wiring style will only work if your humbuckers have 4 conductor wires.
As the install is slightly more complicated than traditional wiring styles and also space is a little tighter to work in due to the additional connections needing to be made, I highly recommend this kit for more experienced modders, or take it to a trusted guitar tech to install on your behalf.
I have intended for my wiring harnesses to be as simple as possible to install to your Les Paul, as well as writing in depth fitting guides, how-to instructions documenting the step by step process as well as a simple to follow wiring diagram.
Will the pots fit? - The parts I use, in particular the pots, are CTS branded pots which are imperial measurements. If you're fitting this harness to a far east built variant for example such as a Epiphone or similar, then you may have to widen the holes in the body to accommodate for these imperial measurement pots.
For reference, the CTS pots I use in this harness have a shaft diameter of 9.52mm.
You may also require new control knobs to fit the CTS pot 'split shaft' spline diameter of 5.95mm(adjustable) with 24 splines.
If you do require US spec control knobs, we do carry a selection of popular options in stock and they can be viewed in the hardware & plastic hardware categories on the store.
The mounting board I ship my harnesses out on, were taken from measurements of a USA build Gibson Les Paul. But I do allow for give in the wire lengths between components, so if your guitar slightly varies from this, then it likely won't be an issue. If it's drastically different to these measurements, feel free to get in touch and we can see about accommodating for that where possible. The centre to centre measurements between components are -
Centre of neck volume pot and neck tone pot - 63mm
Centre of neck volume pot and bridge volume pot - 50mm
Centre of neck tone pot and bridge tone pot - 50mm
Centre of bridge volume pot and bridge tone pot - 61mm
Are my pickups suitable? - For coil split wiring, you will need pickups that facilitate coil split functionality. This is usually possible with '4 Conductor' wires, which means your pickup should have 4 different colour wires coming from it with a bare wire additionally. Unfortunately no two pickup maker uses the same wire colour coding though, so what Seymour Duncan use for their colour coding will be different to bare Knuckle for example. So ensure you have checked that firstly, the pickups are able to facilitate coil splitting, and that you have familiarized yourself with the manufacturers colour coding.
To solder coil split/push pull pots it's ever so slightly more complicated than a bog standard pot. The space is a little tighter, the lugs on the PCB for the coil split wires are fairly small, and sometimes making ground connections can be a bit harder due to the reduced space. I would perhaps recommend this install to a more experienced solderer or feel free to take your guitar to a trusted professional guitar tech to install for you if you're not totally confident.
Long or Short, which do I need?
The question I probably get asked most is, "Will I need long or short shaft pots?". Well Gibson are of course known for lots of transitional changes to specs from the golden era right up to modern day. I have compiled a list of Gibson models which use either Short or Long shaft pots on the individual pot listing HERE But, if you're still not sure, the simplest answer is that ALL types of Gibson or Epiphone Les Paul will fit a long shaft pot, as you can adjust the two supplied nuts to suit the height in the body. All Epiphone Les Paul's with exception of the Elitist model use short shaft pots. Also, feel free to send me a photo of the inside of the control cavity or a photo of the pot itself, hopefully I can help identify it for you.
