Well, I have read many posts of people who have this problem, but I haven't found any one solution, just many opinions. When I play my bass through my bassman 60, I get a loud buzz/hum, which gets louder as I increase volume. This hum goes away if: I turn the tone control all the way down on my bass (MIM Fender Precision), or if I touch something metal on the bass (bridge, volume/tuning knobs, strings, etc) It gets Much louder if I stand near a turned on TV or PC. Is this the result of a bad ground wire near the bridge, or something else? I could always take it to the local dealer, but I would like to hear some of your opinions or past experiances with this. Any input if appreciated.
