An integral part of the Delta Tone™ system on 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 for increased output and overall tonal response. Fits most U.S.- and Mexico-made instruments requiring a 3/8 split-shaft potentiometer. Takes push-on control knob (no set screw). Mounting hardware and .022mf 250V capacitor included.
