Good for standard pots

Works well with standard Bourns and Alpha pots. Just ensure your shaft is indeed 6mm splined before ordering. The lack of markings is perfect for my minimalist setup.

Great quality, slightly tight fit

Excellent build quality and looks very professional. The set screw held firm, though I had to apply a bit of force to get it onto the 6mm shaft initially. Once on, it is very secure.

Solid replacement knob

I needed unmarked knobs for a custom pedal board to keep the aesthetic clean. These are exactly what I was looking for. No wobble and the grip is comfortable.

Premium feel at a good price

Much better than the plastic knobs that came with my kit. The weight gives a nice tactile feedback when turning the volume. Will buy more for future projects.

Exactly as described

Fast shipping and the product matches the description perfectly. The anodizing seems durable and scratch-resistant. A solid choice for any audio equipment repair.

Perfect fit for my vintage amp restoration

The splined shaft fit perfectly on my old potentiometers. The aluminum feels premium and the matte finish matches the chassis beautifully. Highly recommended for DIY audio projects.

5 FAQ

Q: Are these sold in packs or individually?

A: The listing price is for a single unit. If you need multiple knobs for a stereo amplifier or multi-channel mixer, please adjust the quantity in your cart accordingly.

Q: Can I use this for high-power voltage applications?

A: This is a control knob for user interface purposes only. It does not carry electrical current itself; the potentiometer underneath handles the electrical load. Ensure the potentiometer is rated for your specific application.

Q: What is the inner diameter of the hole?

A: The inner diameter is designed to fit a 6mm shaft tightly. The splines inside the knob match standard 6mm splined shaft profiles.

Q: Is the set screw included in the package?

A: Yes, each knob comes with one small set screw required for mounting it onto the potentiometer shaft.

Q: Does this knob fit a smooth round shaft?

A: No, this knob is specifically designed for 6mm splined (D-shaft or multi-spline) potentiometers. It will not securely fit a smooth round shaft.
