Detail 01
500K resistance
Higher value bleeds less treble to ground than 250K, so humbuckers stay bright rather than turning dark.

Proline500K Split Shaft Potentiometer
Independent shopping perspective
The Korena take
A 500K split-shaft potentiometer for repairing or upgrading a guitar's volume or tone control. For anyone doing their own electronics work.
Strong match
Who this is for
- Replacing a scratchy or dead volume pot on a humbucker guitar
- Restoring top-end lost to a worn or wrong-value pot
- Stocking a repair bench with common-value spares
Consider the trade-offs
When to look elsewhere
- Single-coil guitars that voice better on 250K pots
- Anyone without a soldering iron or someone to wire it
- Push-pull coil-split builds, which need a switched pot
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Split shaft
The slotted shaft takes push-on knobs. Set-screw knobs meant for solid shafts won't sit securely on it.
Detail 03
Single pot
One control. A full harness rewire on a two-pickup guitar typically needs four.
Detail 04
Guitar-standard value
500K is the usual choice for humbucker volume and tone. Swapping one changes brightness and taper feel noticeably.
Final check
Know before you order
- 01Requires soldering — desoldering the old pot and transferring wires and cap
- 02No knob, nut, washer, or capacitor included
- 03Check shaft length against your body or pickguard thickness before ordering
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01500K or 250K for my guitar?
500K is the standard for humbuckers and keeps them from sounding dull. 250K is typical on single-coils, where it takes a little edge off the top end.
02Can I use it for volume or tone?
Either. The same pot works in both positions. Tone controls also need a capacitor, which isn't included here.
03What knobs fit it?
Push-on knobs made for split shafts. Set-screw knobs designed for solid shafts won't grip the slotted shaft properly.
04Do I need to solder?
Yes. The old pot has to be desoldered and the wiring, ground, and any tone capacitor moved over. It isn't a drop-in swap.
