So I'm at practice the other night, with my Fender Jazz and I noticed that I couldn't turn the volume off on my bass even though the two control knobs were turned to 0. I fiddled with the tone pot and after some scratching and a pop or two, the bass finally started working properly. I thought that the bass sounded weird afterwards but now that Its home, I cannot say for certain that I can detect anything amiss. Is it possible that I am headed for a problem down the line or is it probable that nothing is wrong and what ever it was that caused that to happen has just 'cleared' itself? My biggest concern is a failure during a gig and the bass becomes totally disabled.
