Detail 01
500K resistance
Higher resistance bleeds less treble to ground. Standard for humbuckers; single-coils on 500K get brighter, sometimes harsh.

ProlineB500K Control Potentiometer
Independent shopping perspective
The Korena take
A 500K audio-taper control pot for guitar wiring. For anyone repairing a scratchy volume or tone control, or building a passive circuit.
Strong match
Who this is for
- Replacing a crackling or dead volume pot on a guitar
- Wiring a humbucker guitar where 500K keeps highs open
- Stocking a repair bench with a common-value spare
Consider the trade-offs
When to look elsewhere
- Players unwilling to solder or pay a tech
- Single-coil guitars voiced around 250K pots
- Active pickup systems, which use much lower values
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
B taper
Linear taper. Volume changes evenly across the sweep instead of staying loud until the last quarter turn.
Detail 03
Potentiometer, not a switch
Works as either a volume or tone control depending on how you wire it into the circuit.
Detail 04
Shaft and bushing sizing
Pot bodies vary in shaft diameter, thread length and knob fit. Measure your existing pot before ordering.
Final check
Know before you order
- 01No knob included. Reuse your old one or buy separately.
- 02Soldering iron and basic wiring skill required; a tech charges for install.
- 03Check your control cavity depth and top thickness for shaft length.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is 500K right for my guitar?
500K is the usual choice for humbuckers, keeping treble intact. Guitars built around single-coils typically use 250K and will sound brighter if you swap to 500K.
02What does the B mean?
B indicates a linear taper, where resistance changes evenly through the rotation. A audio taper is more common for volume; linear is often preferred for tone controls.
03Can I use this for volume or tone?
Both. The same pot works either way, depending on wiring. Only the taper feel changes with the job.
04Does it come with a knob?
No. This is the pot only. Your existing knob may fit depending on shaft type, so check split-shaft versus solid-shaft before assuming.
