Just got one of these and it works great, just seems to be very squeaky...not in the actual signal, but the plastic rubbing against itself seems quite loud. If I have headphones in I can't hear it but my wife started complaining from the other room. Haha. I'm sure it wouldn't be a big deal live but it would be nice to have it quiet. Anyone else have that problem or know an easy fix? Edit: I already tried loosening and tightening the nut that holds the pedal on.
