Pre-Wired bass guitar wiring harness | Bronco 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 bronco 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 the Squier Bronco bass, it's a fun bass right out of the box, but it also makes for a superb modding platform. Even a few simple tweaks can make it a bass not to be overlooked, but I couldn't help but look into the electronics. Needless to say with a bass with a price tag that low, there had to be some components that were of lower quality and the electronics were certainly that. 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. This, along with the McNelly Pickups replacement pickup, specifically designed for Bronco and 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 Bronco, 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. When fitting this to your Squier Bronco, you will 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'. I use Solid Shaft pots for this harness 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 to tone pot - 45mm
Centre of tone pot to centre of jack socket - 45mm
