I’m nearing completion on my rc4 build (build diary http://www.buildyourownguitar.com.au...ead.php?t=8523 here) and had the bass wired up and working... spent about a week noodling around on it with a great deal of satisfaction! The only issues were when the switch was selecting both pick ups there was a slight dip in volume and also with both pups selected, when either volume pot was zeroed it killed all sound (below last 10% of travel). The tones were clean and clear and good differentiation between pups.

Since then I have stripped it down to give it another couple of coats of oil, waxed it and copper taped the control cavity, both pup cavities and the back of the scratchplate.

Once I reconnected everything there is a lot of noise unless both tone controls are zeroed. If the switch is set to both pups either tone pot can be adjusted without noise but as soon as the second gets moved - noise. The same volume issue as before occurs when zeroing one or other volume pot with both pups selected.

Wiggling the lead in the jack socket reduces but does not eliminate noise. I’ve rewired this with new wire with no improvement. I’ve also replaced all other hot wires and checked all connections for connectivity. All cavities are soldered together and there is connection amongst all cavities. The wiring is the same as here although I have the volume pots closest to the strings and the tones at the bottom as this makes more sense to me.

I’m considering replacing the jack socket and all pots but any ideas what’s causing these issues?

Thanks
