Sturdy and stylish

Very solid construction. The matte black finish does not show fingerprints easily. Installation took less than a minute.

Works but color varies

Functionally it works great with the CTS pots, but the black shade is slightly lighter than my existing pickup rings.

Perfect fit for my Stratocaster

The shaft size is exactly what I needed for my US-made guitar. The aluminum feels premium and the grip is excellent during performance.

Excellent upgrade

Replaced the plastic knobs on my bass with these. The difference in feel is night and day. Highly recommended for any DIY project.

Best value for money

You cannot beat this price for an aluminum knob. It looks expensive and feels durable. Will buy more for my other guitars.

Good quality, slightly loose

Great looking knob that matches my hardware perfectly. It fits well but required a tiny bit of tape to make it super tight on the shaft.

5 FAQ

Q: Can I use this for a 500K volume pot?

A: Yes, the knob is compatible with both 250K and 500K potentiometers as long as they have the correct US standard shaft type.

Q: Does this come with a set screw?

A: No, this is a push-on style knob that relies on friction against the split shaft. No set screws are included or needed.

Q: Will this fit a metric shaft potentiometer?

A: No, this knob is designed specifically for US Standard split shafts (approx 6.35mm). It will not fit metric solid or split shafts securely.

Q: Is the aluminum anodized?

A: Yes, the aluminum features a hard-anodized matte black finish to prevent corrosion and wear over time.

Q: What is the exact height of the knob?

A: The total height of the knob from the base to the top is approximately 12mm, making it a low-profile option.
