    I have a Bass Big Muff Pi and the sustain know doesn't seem to work properly anymore. The only thing it does is basically work as a volume know instead of sustain/distortion.

    How can I fix this?
  2. how experienced are you with electronics? have you opened it up and looked for loose connections, dust, dirt or gnomes?

    Maybe the potentiometer that controls the sustain is going bad and needs to be replaced or cleaned out. Deoxit D5 is great to use for electronics cleaning mad specially for it. I sometimes have to spray that into my bass pots every now and then to keep them clean so they don't crackle.

    Sounds like it might be grounding out on something.

    Open it up and take a bunch of pictures of the inside to show us.
