Pre-Wired Guitar wiring harness | Les Paul Junior kit | Right & Left Handed
I usually make harnesses to order, due to the variety of spec options that could be chosen across the range. The waiting time for harness orders is around 3-5 working days depending on quantity of orders in at the time and your order will be updated accordingly when dispatched.
Although the Les Paul Junior may be humble in it's design, it is certainly a tonal monster! 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. After offering a variety of specs over the years, I've now settled on 50s style wiring as standard, with high quality components and a few spec choices which I hope to help the install process that little bit easier.
I have intended for my wiring harnesses to be as simple as possible to install to your Les Paul Junior, as well as writing in depth fitting guides as well as a simple to follow wiring diagram.
The parts I use, in particular the pots, are US made 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 9.5mm.
You may also require new control knobs to fit the CTS pot 'split shaft' spline diameter of 5.95mm.
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 Junior. The centre to centre measurements between components are -
Centre of neck volume pot and neck tone pot - 63mm
With or without Treble Bleed?
First up, what does it do? A Treble Bleed kit takes the 'high' treble tone frequencies out of the circuit at the volume pot, and puts them back in the circuit as the signal leaves the volume pot. This means the treble frequencies are prevented from naturally bleeding out of the circuit as your turn your volume pot down. The result is a smoothed out treble and a more uniform tone from 1 to 10. Reducing the treble drop out as the volume pot rolls off. Some guitar players wouldn't be without a treble bleed, and many have never used one on their guitars. Truth is, it is very much personal preference. I personally don't use a treble bleed mod on any of my guitars, and this is just due to the way I play. If you like the idea of retaining treble as you roll your volume pot down, then a treble bleed is for you!
To note, treble bleeds aren't really needed for fifties style wiring due to the way fifties wiring works. You can have them on if you like and I have included it as a drop down option, but just a heads up!
