Excellent grip

I use these for volume control on stage. The rubber texture prevents my fingers from slipping even when sweating during a gig.

Good quality, slightly tight

The material is excellent and looks professional. They were a bit tight to push on initially, but once seated, they feel very secure.

Great replacement parts

Lost the original knobs for my pedal board switches. These 10mm caps are an exact match and cost a fraction of the price of OEM parts.

Solid build for DIY projects

Used these for a custom synthesizer build. The dimensions are accurate, and the black finish matches most electronic enclosures well.

Perfect fit for my old amp

These caps fit perfectly on my vintage amplifier pots. The rubber feels sturdy and provides a great grip compared to the old plastic ones.

Exactly as described

No complaints here. They arrived quickly, fit the 10mm shafts without wobbling, and look much better than the worn-out originals.

5 FAQ

Q: What is the height of the knob?

A: The total height of the knob cap is approximately 15mm from the base to the top of the dome.

Q: Are these resistant to heat from amplifiers?

A: Yes, the rubber material is heat-resistant and suitable for standard operating temperatures found in guitar amplifiers and electronic equipment.

Q: Do they come in different colors?

A: Currently, this specific model is only available in Matte Black. Please check our store for other knob styles that might offer color variations.

Q: Will these fit a 6mm shaft if I use an adapter?

A: These are designed specifically for 10mm shafts. While you could theoretically use a bushing adapter, we recommend checking the adapter's stability to ensure a snug fit.

Q: Can these be used on outdoor equipment?

A: While the rubber is durable, prolonged exposure to direct UV sunlight or extreme weather may degrade the material over time. They are best suited for indoor electronic use.
