Pre-Wired bass guitar wiring harness | P-Bass kit | Right Handed


Delivery time
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.

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.

Also, I can make this to '54 'Tele' style P Bass specs should you require. It's essentially the same harness but with the measurements between components altered to fit the earlier model of P Bass. If you need one of these, simply order this harness as normal but either drop me an e-mail requesting it, or pop an order comment in the comment box at the checkout :)

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 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 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 9.5mm.
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're opting for the 500k pot spec option, then I use split shaft pots which have a spline shaft diameter of 5.95mm (adjustable). Although you can convert this to 6.35mm with the addition of a brass pot conversion sleeve which are available here.
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.
