    I just finished putting together my first bass, and everything works great, except that when I touch the knobs on any of the pots I get a really nasty hum. I am using a passive jazz type wiring sceme with bart soapbars. any ideas would be appreciated.
     
  2. Have you grounded the pots properly? Often using a wire/copper link soldered to the body of the pot then linked to the next pot is a good grounding measure.

    Make sure there is a good solder connection from your bridge to the ground as well.

    :D:D

  3. The only time you should get an electrical buzz like that is, like Merls said, with a grounding problem.

    What I would do in your case is take a wire and run it through the poys and the output jack to see where it isn't grounding. Make sure you don't cut out the signal entirely though. I had a friend try to wire in new pots to his g****r, and he ran so many wires through he cut out the signal. It was prety funny when he came to me with his guitar. All I did was yank out the one extra wire he had cutting his signal and everything worked just fine again.

    THanks for the input I finally realived that I was a little slow when I wired this thing, and wire the hot and ground backwards to the jack. Because I could still hear the sound of the strings I though it was correct, but I finally figured out what was wrong.
