i have new knobs for my bass, but i dont want to hurt anything taking the old ones off, it looks like they screw on, but i dont want to risk it. Could someone tell me how to change them?
Most of the knobs come off only a couple of ways. They either press-on (no set-screw) or they have a small set-screw in the side of the knob. You loosen this screw, pull the knob off, put the new one on, gently tighten the screw.. Mag...
If they don't have a setscrew, they sometime are a little (or a whole lot) stubborn to get off. there's not a lot to get hold of. Some have to be pried off. If you pull up on only one side of the knob it could damage the pot. Two chuch key type beer can openers work really well. Pad the top with two or three layers of heavy cardboard etc. so the top doesnt dent. use the blunt, angled ends on opposite sides to gently pry up on the knob with a rocking motion and it'll usualy come off.
