i wouldn't worry so much about your problem as me and my friend who is a drummer have the same problem. every time i use my wah pedal i keep looking in the mirror and seeing myself mouthing 'wah wah' which asmuses everyone or i stare quite hard at something. my friend does this so much we nicknamed him 'goldfish' :eek: . all i put it down to is concentration as wen i try not to do this i end up making a mistake so i dont let it bother me.
