Exactly as described

No complaints here. The finish is smooth, and the black color matches my other components perfectly. Fast shipping too.

Good value for money

Solid construction. The only reason I didn't give 5 stars is that the gloss finish shows fingerprints easily, but that's minor. Works great for band switching.

Sturdy and stylish

I bought three of these for a custom synthesizer build. They feel heavy and durable thanks to the copper core. Very satisfied with the purchase.

Premium feel

This knob cap exceeds expectations. The bakelite has that classic look and feel that plastic just can't replicate. Will buy again.

Great quality, slightly tight fit

Beautiful knob with a solid copper core. It was a bit tight on the shaft initially, but after a gentle file, it sits perfectly. Looks premium on my amplifier.

Perfect fit for my vintage radio restore

The bakelite quality is exceptional and feels very authentic. The 6mm hole fit my potentiometer shaft perfectly without any wobble. Highly recommended for restoration projects.

5 FAQ

Q: Will this fit a 1/4 inch shaft?

A: No, this knob is designed specifically for a 6mm inner hole. A 1/4 inch shaft is approximately 6.35mm and will likely be too large.

Q: Is the copper core visible from the outside?

A: No, the copper core is internal to provide weight and durability. The exterior is entirely made of polished black bakelite.

Q: Does it come with a set screw?

A: This model relies on a friction fit for the 6mm shaft and does not include a set screw. If your application requires a screw, you may need to drill and tap it carefully.

Q: What is the outer diameter of the knob?

A: The KN-7 model has an approximate outer diameter of 25mm, making it comfortable for precise adjustments.

Q: Can this withstand high temperatures near tube amps?

A: Bakelite is generally heat resistant, but we recommend ensuring it does not come into direct contact with extremely hot tubes or components to prevent discoloration.
