Alright, so last night I was at my church for praise band practice. I was playing my active p-bass special. Whenever I hit the open e string I would get this crunchy kind of noise from my amp (Ampeg BA210sp). I think it was coming from the horn. It wasn't loud, but I could still hear it pretty well. I thought maybe I needed to change the battery in my bass, but it didn't help at all. This morning I plugged in my passive jazz bass to see if I got the same reaction. No crunchy noise. I don't know anything about this kind of stuff and am curious to see what you guys say. Should I have the local guitar shop take a look at it?
