    I´ve recently purchased a set of model J jazz pickups for my bass. My plan was to wire them up with 2 volumes and one tone knob with push pull functioning as a series/parallel switch.
    I've wired it up using the following schematic.

    The problem I encountered is that it doesn´t work as intended. I triple checked every connection and made sure the grounds are grounded properly. When I plug in the bass I hear a humming sound indicating a faulty ground. The pickups make no sound whatsoever, only the bridge pickup is responsive when both volume knobs are pushed down and the tone knob pulled up.

    I hope one of you can help me resolve this issue.
     
  2. Troubleshooting = removing components until the fault is found
    bypass the treble cut pot
    if that's not it, bypass one of the volume pots
    or you could just jump straight to bypassing it all & wiring one or both pickups directly to the output jack
