What to know before buying

Listing details to confirm

The listing gives conflicting overall pot lengths: 43mm in the features and 46mm in the product description. It also calls the pots 18mm split-shaft in the title while the feature specifies 18mm shaft length. Check these dimensions against the cavity, mounting arrangement and intended knobs before ordering. The title and feature list claim two pots, while the description also lists nuts and a washer, so those small parts are not confirmed in the explicit package information.

Who is it for?

A good fit for

Guitarists or builders seeking a pair of B500K linear-taper push-pull pots for an electric guitar or bass project.
Buyers whose knobs accept a 6mm split shaft and who can confirm the pot dimensions suit their instrument.

Less suited to

Buyers who need a confirmed overall length or confirmed mounting hardware without checking the selected listing.
Installations that require a different resistance, taper or shaft diameter.

Only aggregate ratings are provided, with a small number of ratings and a mix of five-star and three-star scores. That limited, mixed signal does not establish specific strengths or defects. For a fit-sensitive part, the listed shaft details may help buyers compare dimensions, but the conflicting overall lengths remain worth checking.

Frequently asked questions

How many potentiometers are listed?

The title and feature list describe two potentiometers. The product description also mentions nuts and a washer, but the package details do not clearly confirm whether those are included.

What resistance and taper does the listing specify?

It specifies 500K ohm and linear taper.

Will these fit my guitar knobs?

The listing says they fit Stratocaster and Les Paul 6mm knobs and other 6mm knobs. Confirm your knob and instrument mounting dimensions, especially because the stated overall pot length is inconsistent.
