Great aesthetic upgrade

Bought these to replace some generic plastic knobs on my pedalboard. They instantly gave my gear a more professional, classic rock look.

Exactly as described

Fast shipping and the product is exactly as pictured. The dimensions are accurate for a standard round shaft pot. Very happy with this purchase.

Good quality, slightly tight fit

The knob looks great and matches my guitar setup well. It was a bit tight to push onto the shaft initially, but once on, it stays secure.

Solid build

Nice weight to it, doesn't feel cheap. The grip texture helps when making fine volume adjustments during live performances.

Decent but logo fades

The knob functions well and fits fine, but after a few months of heavy use, the silver logo started to wear off slightly. Still usable though.

Perfect replacement for my amp

This knob fits perfectly on my vintage style amplifier. The quality feels solid and the logo looks authentic. Highly recommended for anyone needing a quick fix.

5 FAQ

Q: Is the logo printed or embedded?

A: The logo is printed using a durable silkscreen process, but like any print, it can wear over time with excessive friction.

Q: Does this come with a set screw?

A: Yes, each knob includes a small set screw to secure it firmly to the potentiometer shaft.

Q: Can I use this on a bass guitar?

A: Absolutely, as long as your bass guitar uses standard round shaft potentiometers, this knob will work perfectly.

Q: What is the inner diameter of the hole?

A: The inner diameter is approximately 6mm, which is the standard size for most guitar volume and tone pots.

Q: Will this fit a split shaft potentiometer?

A: No, this knob is designed specifically for round shafts. For split shafts, you would need a different model with a brass insert.
