I've run some searches on this and came up with zilch. When I play aggressive slap-style funk on my 55-01, I can easily turn the volume knob with my flying pinky. Uncool when your volume drops off mid-song. Is is my technique or can I find a volume knob with some resistnace to it so it won't move so easily. I'm thinking of playing with the knob completely removed to avoid contact. Drastic, yes. Being very careful of technique , is of course, what I;m trying to do first. But sometimes, when you're moving fast... HELP!
