Solid construction

Very happy with this purchase. The molding is clean with no flash or imperfections. The set screws provided are good quality steel. They add a premium touch to my home-brew audio interface.

Nice upgrade from stock plastic

Replaced the cheap plastic knobs on my practice amp with these. Immediate visual upgrade. The only reason for 4 stars instead of 5 is that the gold paint on the pointer seems slightly thin, but it still looks great from a distance.

Professional grade components

Using these for a custom mixing console build. The dimensions are precise, and the aesthetic is timeless. They provide excellent grip for fine adjustments during mixing sessions.

Authentic feel and appearance

I restore old radios and amplifiers, and these knobs blend in perfectly with original 1950s components. The material has that distinct warm touch of real bakelite. Highly recommended for restoration projects.

Perfect vintage look for my amp build

These knobs are exactly what I needed for my custom tube amplifier project. The bakelite feels authentic and heavy, not like cheap plastic. The gold pointer is crisp and easy to read against the black background.

Great quality, tight fit

Excellent craftsmanship. They fit snugly on the 6mm shaft. I had to apply a little extra torque to get the set screw tight, but once installed, they don't budge. Looks fantastic on my vintage reissue pedalboard.

5 FAQ

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

A: These knobs are designed specifically for smooth 6mm shafts. They may not fit securely on splined or knurled shafts without modification.

Q: Can I buy these in different colors?

A: Currently, we only offer the Classic Black with Gold Pointer variant. Please check our store periodically for new color releases.

Q: Is this genuine bakelite or a modern synthetic?

A: These are made from high-grade phenolic resin formulated to mimic the properties and appearance of vintage bakelite, offering durability while maintaining the classic aesthetic.

Q: Are the set screws included in the package?

A: Yes, each knob comes with a pre-installed high-quality metal set screw and a small Allen key for installation.

Q: What is the maximum temperature these can withstand?

A: While heat resistant, we recommend avoiding direct contact with extremely hot tubes. They are suitable for standard operating temperatures of audio equipment and guitar amps.
