    My passive jazz amplifies even when both neck and bridge volume are turned all the way down.

    Is this normal? If, not what can I do to fix this?

    Thanks TBers.

    Certainly not normal. Is it still amplifying at a very noticeable volume, or is it just slight?

    Significantly enough to where I have to turn amp col all the way down.

    is your bass active? I noticed this happening with my ray 4 but won't do it with any passive basses.
     
  5. Check the wiring. Check with a multimeter if the pots behave correctly.

    Did you tap the pickups with both volumes down? Are both amplifying or just one? This will help you track down the problem. My guess is that it's one of the pots

    a vol pot is probably not connected to ground. check the wiring for a broken connection or bad soldering.

    I thought you meant "when the knob is off the bass." Like, physically off. :D
     
  9. Probably this.
