hey everyone...the volume knob on my ibanez soundgear 805 seems to send a loud pop through my amp when i turn, or sometimes touch it. now i tried my hardest to tighten that nut/washer or whatever it is under it, but its a tight little area. anyone know if the knob is removable and how to do it if it is??...i know on my p-bass you just pull the darn thing off. Thanks for all your help--keep it on the low end.
