Black nylon plastic with a matte finish and slight grainy feel.
About this Product
This knob is very different from most of the designs available in the market today. It has a unique feel to it, kind of like massaging balls for your fingers. 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. This is a great original design that will make your guitar or bass standout. The functionality is not sacrificed over design.
