Alright, I officially can't stand this any longer. Whenever I just have the bass sitting there it hisses. Adding treble makes it hiss even louder. And it drives me insane with my loops. Do I need to take this bass to a professional to have it shielded properly or can I do it myself without completely destroying my instrument? For the record: if I opened up my bass I have no idea what I'm doing, so I'd rather take it to a professional if that's what it's going to take.
