Pre-Wired Guitar wiring harness | 50s SG kit | Right Handed & Left Handed
I usually make harnesses to order, due to the variety of spec options that could be chosen across the whole range. The turnaround time for a harness orders is around 3 working days depending on quantity of orders in at the time and your order will be updated accordingly when it is dispatched. This turnaround time doesn't include the transit time. Thanks for your patience whilst I get your harness made!
SGs must have looked like such a unique design upon their launch, the thin body, pointed horns and incredible upper fret access. A big jump from the original Les Paul for which it was originally introduced as a replacement for. I've spent a lot of time refining the specs of this harness to ensure the best from the guitar and an easy install. 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 SG, 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.
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.
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 SG. The centre to centre measurements between components are -
Centre to centre measurements between components are -
Centre of Switch to neck volume pot - 55mm
Centre of switch to bridge volume pot - 55mm
Centre of neck volume pot to centre of neck tone pot - 50mm

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. 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 as some customers still request them, but just a heads up!
.01uF or .022uF neck position tone cap value?
Troubled by a dark sounding neck pickup? Well it's not totally un-common with Gibson type guitars or humbuckers in general so don't worry, you have some ways in which it can be improved. Although the standard spec harness will I'm sure help the pickup breathe and is ultimately the most popular spec choice, I now also with the choice of a .01uF value cap in the neck position instead to help clear up a darker sounding neck pickup.
This is very much personal choice and/or how you are finding the balance between the neck and bridge pickup currently. The main thing to consider is whether you feel your neck pickup is too dark/muddy compared to the bridge pickup. If it is and you want to try and help brighten it up a little, then a .01uF value cap in that position may be useful to you. If you like how your neck pickup sounds, then stick with a .022uF! It's the most popular choice and the 'go-to' cap value for most P90s and Humbuckers generally.
Righty or Southpaw, the choice is there to suit however your play!
Alongside the usual right handed replacement wiring harnesses, I also make these in left handed orientation. After a lot of research and customer orders over the years it seems 99.9% of Lefty players are used to using guitars with traditional RH taper pots. This is mainly because many guitar manufacturers simply fitted RH taper pots in LH taper guitars. But some LH players do of course prefer using LH taper pots, whatever your preference as a Left handed Strat player, I offer the spec to suit.
