Just bought my first Hotcake pedal and the damn thing plum killed my volume. I tried changing the socket on the pedal power 2 but it's 9v and working fine, tried moving it in the signal chain, turned the amp way up and could *just* hear my signal. Then in frustration, I jabbed the Hotcake with my foot, and BOOM! I'm not sure if it was the blast of sound from the amp or if I got an electric shock, but my fillings hurt. Anyway, it seems that rolling the volume knob does nothing, but pressing it down seems to be reconnecting a circuit and allowing the pedal to operate normally. Is this loose knob something I can fix myself, or do I have to drive 40 miles to the store again to replace it?
