This is a guitar knob I designed; I call it Mod knob. This guitar knob will work for volume and tone control on your guitar. I love the design on this knob. It will fit any potentiometer up to 1/4” diameter. It is designed to self tap with a 6-32 set screw, if the part is ordered in plastic. If the part is made out of metal you may need a 6-32 tap. This little knob will make your guitar look assume. The functionality is not sacrificed over design.
