It is the secret weapon on this box, everybody. I've had mine for a month and haven't had the courage to go under the hood. The PCB is attached to the backplate and I didn't want to risk bricking a $250 pedal and waiting weeks to repair due to a snapped solder connection or what have you. Turns out a previous owner had turned the trim all the way back, decapitating all of the sparkle in the attacks. I dove in, brought it back up and.... Do it! No fear!
