Pre-Wired Guitar wiring harness | J-Bass kit | Right Handed


Order times
I usually make harnesses to order, due to the variety of spec options that could be chosen across the whole range. The current turnaround time for a harness orders is around 5-7 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!

The introduction of my harness for Jazz Bass was to compliment the models of McNelly J Bass pickups that I also offer, and I wanted a quality upgrade for your wiring that would work well with those great pickups. It's a simple recipe of the highest quality components to bring the best out in your bass. As standard I offer this harness with the traditionally used 250k pot rating and features the traditional spec of individual volume control for each pickup and a master tone control.

I have intended for my wiring harnesses to be as simple as possible to install to your J-Bass, 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 CTS branded pots which are imperial measurements. If you're fitting this harness to a far east built variant for example such as a Squier or similar, then you may have to widen the holes in the control plate 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 'splines'. If you're opting for the traditional 250k pot spec, then I use Solid Shaft pots which have a shaft diameter of 6.35mm.
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.

Centre to centre measurements between components are - 
Centre of Volume pot 1 to centre of volume pot 2 - 35mm
Centre of Volume pot 2 to centre of tone pot - 35mm
Centre of tone pot to centre of jack socket - 35mm
