About a year ago I started asking about this funny weird distortion from my Ampeg BA115. I've taken it to shop about 3 times and they could never find the problem and said dirty pots everytime. I've checked everything on the amp until recently read someone hear had the same issue and found it was the tweeter. I am done with this amp and had enough of this. I've been looking for a new amp since this one has been slowly dieing on me. I've had it for about a year and a half. Once this sound started it was the begining of the end. Volume drops and spikes, uncontrolable mud tone at high volumes. And I'm going to need a more dependable amp since my band is looking to gig now. So here's my questions. Is it possible to buy a new tweeter and how much do they cost and where should I look. I've been looking at a Acoustic head the B200 and think that should be enough for me for a while until I can afford a "pro" setup. What cab would be a good match? I want a 1 15 since I play in a dual guitar band. And are there any issues with this head? Any help is good. And have a budget for about 500 bucks.
