Good but color varies slightly

The knob works well and fits fine, but the black shade is slightly different from the other vintage knobs I have. It's more of a charcoal than a deep jet black. Still usable though.

Excellent grip and feel

I replaced the plastic knobs on my mixer with these. The textured surface provides much better control when adjusting levels quickly. They add a nice touch of class to the equipment.

Perfect vintage look for my build

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

Great quality, slightly tight fit

The aesthetic is spot on for vintage gear. The only reason for 4 stars is that the hole was a tiny bit tight for some of my older pots, but a little reaming fixed it instantly. Looks fantastic once installed.

Best replacement knobs available

I bought a batch of ten for a console refurbishment. Consistency across all units was perfect. They feel heavy and durable, exactly like the originals from the 60s.

Sturdy and well-made

Very impressed with the build quality. No mold lines or defects. The white indicator line is crisp and easy to see even in low light conditions. Highly recommended for any audio restoration.

5 FAQ

Q: Is there a setscrew included to secure the knob?

A: This model primarily uses a friction push-on fit, but it features a molded indentation where a setscrew can be added if desired. The screw itself is not included in the package.

Q: Do you offer these in other colors?

A: Currently, we only stock the Classic Black with White Indicator version. Please check our store periodically as we may introduce new color variations in the future.

Q: Can these withstand high heat from tube amps?

A: Bakelite is a thermoset plastic known for excellent heat resistance and electrical insulation properties, making it perfectly suitable for use near tube amplifier components.

Q: Will this fit a standard guitar potentiometer?

A: Yes, this knob is designed to fit standard 6.35mm (1/4 inch) split shaft potentiometers commonly found in guitars and amplifiers.

Q: What is the inner diameter of the shaft hole?

A: The inner diameter is approximately 6.35mm to accommodate standard split shafts. If your shaft is solid or metric, you may need an adapter bushing.
