The knobs turn easily, so they move when I accidentally hit them during a show. What can I do?

I recommend lowering the knob so that it rubs against the pot nut, making it harder to turn and shouldn't move on it's own.


Some customers also put a felt washer between the knob and the nut to increase physical resistance.


Our knobs have little set screws in them loosen this with a 1/16 hex key, lower it down as far as it will go and then tighten it again. You're done!
