Description
When a stacked knob on your Fender amp starts crackling, skipping, or just quits responding smoothly, chances are the concentric pot underneath is worn out. This is Fender’s own replacement: a dual-section 250K/500K potentiometer built with a solid shaft, designed to slot back into the concentric control layouts found on select Fender amplifiers.
- Dual-gang concentric design — two independent resistance values in one unit
- 250K and 500K sections for accurate tone/volume taper matching
- Solid shaft construction for durable, direct mechanical feel
- Fender-specified part, built to original electrical spec
Because it’s a concentric pot, you’re really replacing two controls at once — so it’s worth checking exactly which stacked knob assembly on your amp uses this value combination before ordering. Swapping in a fresh, correctly-rated pot restores smooth rotation and eliminates the scratchy pops that come from worn wiper contacts, without altering how the amp was originally voiced.
A straightforward fix for players who’d rather solder in a proper part than live with a flaky control. Keep one in the parts bin — concentric pots are exactly the kind of small component that fails at the worst possible time before a gig.
