Great quality, slightly tight fit

The aesthetic is fantastic and matches the retro vibe of my pedalboard perfectly. The only reason for 4 stars is that the hole was a tiny bit tight for my specific pots, requiring a gentle ream, but it holds very well now.

Perfect vintage look for my amp build

These knobs are exactly what I needed for my custom tube amplifier project. The bakelite feels solid and authentic, not like cheap plastic. The fit on the potentiometer shaft is snug and secure.

Classic style

Nothing beats the look of real bakelite. These add a professional touch to any audio gear. Shipping was fast and the packaging protected the item well.

Good value for money

For the price, you get a high-quality component. It looks much more expensive than it is. Works great on my guitar volume control.

Excellent durability

I have replaced all the knobs on my mixing console with these. They withstand daily use in a busy studio environment without showing wear. The white indicator line is crisp and easy to read.

Authentic feel

As someone who restores old radios and amps, I can say these reproduce the original feel and weight of vintage knobs accurately. Highly recommended for restoration projects.

5 FAQ

Q: Can these be used on DC power switches?

A: While primarily designed for audio potentiometers, they can be used on switches provided the shaft diameter matches the 6.35mm specification.

Q: Do you offer these in other colors?

A: Currently, we only stock the Vintage Black version with a white indicator. Please check our store periodically for new color releases.

Q: What is the return policy if the size is wrong?

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

Q: Will this fit a standard CTS potentiometer?

A: Yes, this knob is designed to fit standard 6.35mm (1/4 inch) split shaft potentiometers, which includes most CTS models used in audio equipment.

Q: Is the white line painted or molded into the material?

A: The white indicator line is molded into the bakelite during manufacturing, ensuring it will not fade or chip off over time.
