Good value

Does exactly what it is supposed to do. The plastic feels a bit lighter than the original manufacturer part, but for the price, it's a solid buy.

Essential spare part

Every guitarist should have a few of these in their toolbox. You never know when a knob will break at a gig. Highly recommended.

Perfect fit for my old pedal

I lost the original knob on my vintage delay pedal. This 6.4mm cap fit perfectly onto the shaft and feels very secure. Great replacement part.

A little loose

It fits, but it's slightly looser than I expected. I had to add a tiny bit of tape to the shaft to make it snug. Works fine now though.

Standard size works great

If you have a standard quarter-inch shaft, this is the one to get. Simple, effective, and looks clean on the faceplate.

Saved my amp repair

Needed a quick fix for a broken volume knob on my practice amp. Arrived fast and snapped right on. No slipping during adjustments.

5 FAQ

Q: Is this compatible with Fender amplifier knobs?

A: Yes, most Fender amplifiers use standard 6.4mm shafts, so this knob should fit perfectly on volume and tone controls.

Q: Does it come with a set screw?

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

Q: Can I use this for a radio volume dial?

A: Absolutely, as long as the radio potentiometer has a 6.4mm shaft, this knob is suitable for radios, guitars, and other audio equipment.

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

A: This knob is specifically designed for 6.4mm (1/4 inch) shafts. It may be too loose for a 6mm shaft without additional adaptation.

Q: What is the return policy if the size is wrong?

A: We offer a 30-day return policy for unused items. Please check your shaft diameter carefully before ordering to ensure compatibility.
