now i've lurked and lurked but all i can find is threads on the popping due to a faulty preamp or cable, or grounding. It's not my bass ( as i've got two and it happens on both, and it happens even when im not plugged in ), resolving that it's not my cable. What's going on? my amp pops. And by pop i dont mean little crackling, i mean loud pops. oh, and for as long as i can remember it ive had a quiet kind of fuzz or humming in the background whenever the amp is on too. Any quick fixes, or...fixes?
