The custom series 500K SHORT/split potentiometers feature a knurled shaft and audio taper, packaged in a set of four with included hardware: nut, dress washer, and lock washer. Designed for guitars, these pots are high-quality, ideal for tone and volume controls. They offer specifications such as 500K Ohms/10% Tolerance, Bakelite base plate, solid brass c-clip reinforced shaft, and a 3/8-32 US thread with a 3/8" (short shaft) bushing height. The pots have a split, fine 24-tooth knurled shaft measuring 1/4" in diameter. Installation requires a 3/8" diameter mounting hole and a chamfered shaft tip to facilitate knob installation without sticking.
