Pre-Wired bass guitar wiring harness | Musicmaster 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.

Harness & Pickup deal set - If you are ordering the harness with the McNelly Musicmaster bass pickup as well, please note potential additional delivery time of 10-12 weeks for pickup to be made and arrive in the UK if I don't currently have stock. 

I am a big fan of short scale basses, and the Musicmaster is one of the best!, So I looked at creating a 'drop-in' wiring harness upgrade, using the high quality components I use on my other harnesses such as CTS 'TVT' pots, Pure Tone multi contact jack, Gavitt wire and SoZo Mustard tone capacitor.
But I have also decided to offer it as part of a complete wiring upgrade packaging along with the McNelly Pickups replacement pickup, specifically designed for Musicmaster turns this bass into a serious tonal instrument.

I have intended for my wiring harnesses to be as simple as possible to install to your Musicmaster, 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. You may have to widen the holes in your pickguard to accommodate for this depending on it's original specs.
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'. I use Solid Shaft pots for this harness which have a shaft diameter of 6.35mm. If you would prefer split shaft pots (5.95mm 24 spline for push fit control knobs) do please just ask, but as standard this kit comes with solid shaft pots.

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 to centre of tone pot - 41mm
Centre of tone pot to centre of jack socket - 34mm
