I have a John Petrucci Signature Mystic Dream (+piezo). While adjusting the volume - up and down- I get a rustling (noise) sound. Also it happens on the tremolo arm. How can I solve this problem?
Is it a "scratchy" noise, like a bad pot? Or does it sound like a grounding issue, like random noise when you touch the strings, bridge, pot or anything metal?
Slide the rubber ring DOWN to access the set screw, otherwise it is easy to break or overstretch the band if you try and take it off the top of the knob.
