Perfect fit for my old pedal

I lost the original knob on my delay pedal and this was a exact replacement. The 6.4mm shaft fits snugly without being too tight. Great value for the price.

Exactly as described

Fast shipping and the product is exactly as pictured. It's a simple plastic knob but it does the job perfectly for adjusting volume on my amp simulator pedal.

Works but feels cheap

It functions fine and stays on the shaft, but the plastic feels a bit lighter than I expected. For the low price though, I can't complain too much.

Good quality, slightly loose

The knob looks great and matches my setup well. It fits the shaft but is just a tiny bit loose compared to the factory part. A small piece of tape fixed it right up.

Saved my vintage radio project

Used this for a restoration project on an old tube radio. The size is spot on for standard audio potentiometers. Very happy with the purchase.

Great spare to have in the drawer

I bought a few of these to keep in my toolkit. You never know when you'll lose a knob during a gig or session. These are standard size and work on almost everything.

5 FAQ

Q: Will this fit a potentiometer with a 6mm shaft?

A: This knob is designed specifically for a 6.4mm (1/4 inch) shaft. It may be too loose for a 6mm shaft and could slip off easily.

Q: Can I use this for a car stereo volume knob?

A: Yes, as long as your car stereo uses a standard 6.4mm D-shaft or round shaft potentiometer, this knob should fit correctly.

Q: Does this come with a set screw to secure it?

A: No, this is a push-on style knob that relies on friction to stay in place. It does not include a set screw.

Q: Is the black color matte or glossy?

A: The finish is a semi-matte black, which helps reduce glare on stage and matches most standard effect pedals.

Q: How deep is the hole inside the knob?

A: The internal depth is approximately 12mm, which is sufficient for most standard audio taper pots used in guitars and radios.
