Perfect upgrade for my Strat

These knobs feel incredibly solid compared to the stock plastic ones. The brushed chrome finish matches my hardware perfectly, and the set screw holds tight without slipping.

Good but check your shaft size

The knobs are beautiful and well-made, but make sure you have split shaft pots. They did not fit my solid shaft potentiometers without modification.

Great quality, slightly tight fit

The metal construction is top-notch and looks very professional. The only reason for 4 stars is that the set screw was a bit difficult to tighten initially, but once set, it's secure.

Sturdy and stylish

Replaced all four knobs on my Les Paul copy. The metal feels durable and the chrome shine really pops under stage lights. Highly recommended for DIY upgrades.

Excellent value for money

I bought these for a bass guitar project. They add a nice weight to the instrument and the grip texture makes volume swells much easier to control.

Looks premium

These transformed the look of my budget guitar instantly. The set screw mechanism is much more reliable than push-on knobs. Very happy with this purchase.

5 FAQ

Q: Is the finish prone to tarnishing over time?

A: The brushed chrome finish is treated to resist tarnishing and corrosion. With normal use, it should maintain its appearance for years.

Q: Can I use these on a pedal with a solid shaft?

A: No, these knobs require a split shaft with a groove for the set screw to grip. They will not securely attach to a smooth solid shaft.

Q: What is the return policy if the color doesn't match my guitar?

A: We offer a 30-day return policy for unused items in their original packaging. Please contact our support team to initiate a return.

Q: Does the package include the tool needed to tighten the screws?

A: Yes, each pack includes a small Allen key specifically sized for the set screws on these knobs.

Q: Will these fit standard CTS potentiometers?

A: Yes, these knobs are designed to fit standard 6mm split shaft potentiometers, which includes most CTS models used in electric guitars and basses.
