Right now the volume pots don't work like they should. Thinking I need to start again, from scratch, what I want is a volume and tone on each pickup, and a switch to either send both outputs to tip as per normal or send one pickup to the ring of a stereo jack, it works fine on my other bass, but that has no tones, and P + j pickups. Does having tones make a difference? Its in bits again no, gotta put it back together and try and describe better how all the knowbs currently work.
Edit: How would I wire the switch in the Jazz style scenario?
Edit 2 it works fine in stereo mode, but in mono either volume takes all the sound if you turn down, suspect its the ring contact to the shaft causing it but having trouble picturing it now its all back together. Maplins for a double pole switch so I can isolate it next rebuild.
