An integral part of the Delta Tone™ system of Fender American series electric guitars, this 250K "no-load" potentiometer functions as a normal tone control from 1 to 9. At 10, the tone control is removed from the circuit to increase output and overall tonal response. Fits most US and Mexican made instruments requiring a 3/8" split shaft potentiometer. Takes a push-on control knob (no set screws). Mounting hardware and 0.022 mf capacitor 250 V included.
