I used my amp yesterday morning and it was working fine. I then went to band practice and hooked everything up like normal and the amp was not functioning, just making clicking sounds. All four tone lights are lit up along with the Bluetooth. I use a FBV short board along with it. I tried to reset it by pushing the volume and tone buttons while starting up, and tried to update it via computer (which my PC was not recognizing it ) with no luck. Does anyone have any other solutions? It should be still under warranty since I purchased it on march 10th of 2014. Thanks for any input!
