I do outdoor gigs the pedal activated volume control goes haywire and is either full on (regardless of pedal position) or inconsistently on and off, it appears that it has to do with sunlight interfering with the operation of the expression pedal. I have had to use a towel over the expression pedal to block the sun for it to function correctly. Does anyone know of a fix for this problem?
