Hi, New user here...
So the story is, I recently bought a used Acoustic G100FX from Musicians Friend. When the amp arrived, I plugged into the LOW input jack, played for about 5-10 minutes, and the amp made a loud pop, guitar signal was gone. I cut the amp off, plugged into the HIGH input, tried playing again for about 5-10 minutes... same thing. I read about possible FX loop trouble, so I plugged into the FX return to try bypassing the preamp section. This is the only way I've been able to get the amp to work consistently without dropping the signal. I have a pretty good idea that the problem is in the preamp section, as the amp and speaker still get power after the signal is dropped. I also broke into the amp and checked all the fuzes to make sure, they all checked out. Anyone ever have anything similar happen, or have any idea of where to go next in the troubleshooting process?
