    I'm working on this jazz bass, and the problem with it is that the tone pot doesn't work, it's just always turned down. But this only happens when the control plate is screwed onto the bass. Whenever I take it off, it starts working perfectly how it should. Anybody have any suggestions of what to do? I can't really think of what the problem could be.

    Bare bit of wire touching something it shouldn't when you stuff it into the cavity.

    Check your solder connections /loose frayed wire. (Same problem last week with volume pot)
  4. Either a bare part of a wire or a part of a pot is touching the shielding paint inside the control cavity causing a ground.

    I had same issue and just taped off the inside of the control cavity with rubber tape. Problem solved.

    Look for something that could be shorting the middle leg of the tone cap to the leg where the capacitor is connected. Not just at the pot, but follow the wires back to the volume pots.

    Also could be a wire that's stretched when installed (so something shorts), but not when you take things apart.
