Les Paul Guitar Wiring Harness

Quality Les Paul wiring kit for your Gibson, Epiphone or Les Paul copy.


Where it all began…

It was 1952 when Les Paul debuted the first Gibson Les Paul guitar to the world. The original model featured P90 pickups and the ever-popular gold top finish. By 1957 the P90 pickups were replaced by a new style of pickup – the humbucker. An unmistakable icon had been born which would go on to help shape guitars and the music they create for the next 60 years.

The way in which the Les Pauls wiring and electronics work has not really changed since they were first created. But fortunately manufacturing processes and the quality of components which can be used has improved.

The electrical low-down…

The electrical components inside your guitar are almost never seen and thus, easily forgotten. A number of large guitar manufacturers know this and often “skimp” on the quality of components used and the way they wire them to save on costs.

Something not every player considers…

Replacing your guitar’s pickups is an easy way to improve or alter your tone. But what a lot of players don’t think about is how their signal is carried from the pickups to the amp.

Your signal passes through the guitars wiring harness before travelling to your amp. You do not want crappy components or dodgy wiring robbing you of tone!

This is where Guitar Sauce comes in…

I build your wiring harnesses using the best premium components available and I build them with 110% attention to detail. I also offer unlimited support for the lifetime of your harness.

Your new wiring harness will also help if your guitar is suffering from any of the following:

  • Scratchy pots
  • Signal cuts in and out
  • Tone controls make no difference to your tone
  • Tone becomes too muddy when rolling back the volume
  • Volume or tone controls have no “sweep” and are very abrupt

Your Les Paul wiring harness includes:

4x Premium CTS 500k audio pots
I’ve tried CTS pots from various suppliers and these are the best I have found. Solid brass shaft and bushing. C-clip reinforced shaft and a 30% taper which offers a perfect sweep. I make sure they are all matched to within a +/- 2% tolerance.

Switchcraft straight toggle switch
The best toggle switch around. These are robust and will last for years.

2x Sprague Orange Drop .022uf capacitors
The classic capacitor used since the 1960’s. Known for their tone and reliability, these capacitors are used by many high-end guitar manufacturers and builders around the world.

Switchcraft mono output jack
The industry standard for output jacks. Solid and dependable.

Vintage style cloth covered 22 gauge black wiring
This quality vintage style wiring is pre-tinned which means it holds its shape and makes soldering a lot easier for you.

All kits are wired with 50’s style wiring.

Some extra info to help you out…

Pot shaft length and switch length

It’s important to know what “size” pots and switch your guitar currently uses. If you order the wrong size they may not fit inside your guitar.

I have created an easy guide which illustrates the difference between long shaft and short shaft guitar pots and shows you how to check what size you need before ordering.

Or do you need help deciding which switch type you need? Visit my blog post on guitar toggle switch types to determine which size you need.

Compatibility with your guitar

Your new wiring kit will fit directly into American made Gibson Les Pauls and any other Les Paul style guitar which use imperial sized pots.

If your guitar is an Epiphone Les Paul or a Les Paul style guitar which currently uses metric sized pots then you will need to slightly widen the holes in the body to fit the upgraded CTS pots.

I have written a helpful guide here which covers the difference between imperial and metric guitar pots, how to check your current pots, and making sure your knobs will fit your new pots.

    I’m very happy with the harness it has improved the overall tone without a doubt. I love the way it sounds now and it has now become my number 1 guitar!

    It really sounds incredible compared to before.

    The sound used to be quite thin and lacking, but the new wiring draws so much more out of the pickups.

    The new capacitors are a lot larger than the old ones and the cloth covered wiring feels stronger. The wire itself too is thicker which is nice. It’s just a huge improvement to this Epi and I’m sorely tempted to install some hand-wound pickups now.

    This particular guitar was never wired correctly and had a pretty average sound. After the install of your harness it’s breathed new life into it … sounds awesome!

    I’m super impressed with the new wiring kit! Previously, my Epiphone Les Paul Standard was quite dark and muddy sounding, but this wiring harness has opened up the sound and sounds nice and clear now.

    The nice, thick cloth wiring feels solid too, and the whole lot was incredibly easy to install. I’m super impressed and I would happily recommend others use this kit to upgrade their tone! Thanks!

    Yes, another review from me. This time, I installed this wiring kit into an Epiphone ’56 Gold Top with P-90 pickups, and The difference in tone is huge!

    The clarity this guitar has now is really something special, and it just sounds wonderful!

    If you have an LP with P-90’s, I would definitely recommend this kit. Thanks again!

    The wiring kit is in, no trouble at all, the clear labeling, including pickup wiring points meant it was done in 30 minutes.

    My Chinese knock off LP is now clean and clear, no longer muddy and dull with no tone control.

    P.s. was very well packaged and very professionally laid out, very impressed indeed.
