Beautiful craftsmanship

The attention to detail is impressive. The edges are smooth, and the pointer line is perfectly straight. These add a nice touch of class to any audio gear.

Perfect vintage look for my amp

These knobs transformed the look of my old tube amplifier. The bakelite feels authentic and sturdy, not like cheap plastic. The 6mm hole fit my pots perfectly without any wobble.

Great quality, slight color variation

Really happy with the build quality. They feel heavy and premium. One knob was slightly darker than the others, but it's barely noticeable once installed on the guitar.

Solid fit and finish

No issues with installation. They push on easily and the set screw holds them tight. The gloss finish looks fantastic under stage lights.

Good value for money

For the price, you get four really nice knobs. They aren't genuine vintage, but they mimic the style very well. My pedalboard looks much more professional now.

Exactly what I needed for restoration

I am restoring a 1970s mixer and these knobs are spot on. The gold pointer is crisp and easy to read. Highly recommend for anyone doing vintage audio repairs.

5 FAQ

Q: Do you sell matching pointer caps in different colors?

A: Currently, this specific model only comes with the gold pointer. We do have other listings with silver or white pointers if you search our store catalog.

Q: Are these made of real bakelite or plastic?

A: They are made from high-quality synthetic bakelite resin that mimics the look and feel of vintage material while offering better durability and consistency than original aged bakelite.

Q: Will these fit a potentiometer with a splined shaft?

A: These knobs are designed primarily for smooth 6mm shafts. While they can be forced onto splined shafts, we recommend using smooth shaft pots for the best fit and to avoid damaging the knob interior.

Q: Can I use these for volume control on an electric guitar?

A: Yes, absolutely. As long as your guitar's potentiometer has a 6mm smooth shaft, these knobs will work perfectly for volume or tone control.

Q: What is the maximum temperature these can withstand?

A: These bakelite knobs are heat resistant up to approximately 150°C (300°F), making them suitable for use near vacuum tubes where moderate heat is present, but direct contact with hot tube glass should still be avoided.
