I have a shortboard mk1 i use with my spider valve amp. All of a sudden, the pedal doesn't function as either a volume or wah. There is volume at the amp, and all of the other buttons on the shortboard work fine. When I try to calibrate the pedal, the numbers come up on the screen, but when you rock the pedal, nothing happens, none of the numbers change. Is there a fix for this, or is it time for a new board, which would really suck because it's not abused or anything like that.
