Sometimes when I'm using the drive channel the amp starts loosing drive and switches to clean channel without the lights on the amp or the footswitch switching to the clean channel. I tried using it with the guitar directly plugged into the amp without the pedalboard or any pedals in between and it still happened. This happens sometimes, usually I turn it of for a couple of minutes and then on and no problem. Could the cable going from the amp to the footswitch be a factor?
