Hey guys! I was doing searches about broken BA-115 combo amps, but couldn't find anything that was relevant to my question/problem. I have a BA-115 that crackles when I turn the volume anything higher than half-way. This started to happen after a drunken friend of mine fell on top of my amp and knocked it over. I don't know anything about electronics or how to diagnose the problem. Who can I take my amp to to get it fixed? I'm hesitant about guitar center because choads predominately work there and I'm not prepared to get ripped off as well. Any suggestions?
