I bought an Acoustic B200 about a year ago and really liked everything about it. I never had a problem with it, until about 2 months ago. I started getting this strange high pitched whistle rattle. (Think Jetson's car sound that is the best way to describe it.) I though it had something to do with my bass, but I wasnt sure. I took it into my local GC and plugged into it with a different bass, and it was making the same sound. The guy immediately said "it might be a speaker problem, not sure, so I'll just get you a new one". GREAT deal! Took the new one home, started playing on it, and already, not 2 months later, this one is doing it too. I'm so frustrated. I don't know what the deal is, and will probably just take it back and tell them its doing the same thing. Thing is, do I try a 3rd one? Or do I ask for my money back and put it towards something else? If they would even do that. Advice?
