This is a guitar knob I designed; I call it Turntable knob. This guitar knob will work for volume and tone control on your guitar. This knob has a great feel and very stylish. It will fit any potentiometer up to ¼” 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. The guitar knob is out of the ordinary yet the functionality is not sacrificed over design.
