Am I misunderstanding something? I don't understand how someone can use both inputs. The manual clearly states that if both inputs are used the amp switches to normal gain mode (6dB pad). From the manual - "Situations where both inputs are used simultaneously (alternating between two guitars on stage using both inputs, etc.) should be avoided if peak overdrive is expected from the amp." According to that you're actually always in normal gain mode if you have cords attached to both inputs, right?
