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.
