Pre-Wired bass guitar wiring harness | P-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 Precision Bass was to compliment the models of McNelly P 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, but I had a few customer requests for 500k pots, so I now also offer that as an option for the customer. As standard I also use a .022uF, but if you have a particular preference then no worries at all! Just drop a comment in the box during checkout or email me and I can wire in your preferred spec, .047uF or 0.1uF for example no worries.

I have intended for my wiring harnesses to be as simple as possible to install to your P-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 pickguard 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'. I offer this harness with split or solid shafts. The split shaft pots are 5.95mm 24 spline, and the solid shaft are 6.35mm solid.

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 (there is 'give' in wire lengths allowed for slight variations to this) - 
Centre of Volume pot to centre of tone pot - 53mm
Centre of tone pot to centre of jack socket - 53mm

These measurements were taken from a Genuine Fender P-Bass pickguard, and I also allow for some 'wiggle' room in the wire lengths to help make a comfortable fit in a variety of models. But if these measurements are way different to those on your pickguard, no problem at all! Just get in touch with the centre to centre measurements as listed above but on your bass, and I can accommodate for that no problem.
