Fender 500K Solid Shaft Pot (Volume or Tone) 3/8" w/ .022mf 250V Cap & Mounting Hardware

Restore Volume or Tone Control in Compatible Solid-Shaft Circuits

The Fender 500K Solid Shaft Pot is a replacement potentiometer for compatible Fender instruments requiring a 3/8" solid-shaft control. A 500K pot is usually associated with humbucking pickups, where the higher resistance value can help retain more high-frequency detail than lower-value control pots.

Used as a volume or tone control, the potentiometer affects how the guitar’s signal is shaped as the knob is turned. This makes the correct value and shaft type important when repairing a worn control, replacing a noisy pot, or maintaining the expected response of a humbucker-equipped circuit.

The solid-shaft design is made for set screw-mount control knobs, so compatibility depends on both the control cavity requirement and the knob type. The package includes the mounting nut, washer, and a .022mf 250V tone capacitor, giving repairers the key parts needed for many standard wiring jobs.

At Riffs & Licks Music, we think this pot is best for players or repairers working on compatible humbucker-equipped Fender instruments, because the 500K value helps preserve clarity while restoring smooth volume or tone control function.
