I was playing a show last weekend and my OCD crapped out on me. I have the version 3 and it is in an MKS Pedalpad 2 and well protected. Anyway, here is the problem; When I step on the box, the light comes on, but no sound. If I step on it hard, sometimes the sound comes through fine. I don't think that it is a patch cable, because when the pedal is disengaged there are no problems. Does anyone know what this could be and how to fix it?
