Exactly as described

Fits the 1/4 inch shaft snugly. The matte black finish matches my pedalboard perfectly. Installation took less than a minute with the included tool.

Aesthetic and functional

Looks amazing on my custom build. The weight adds a nice tactile feedback to the potentiometer movement. Highly recommend for anyone modding their gear.

Perfect fit for my Fender amp

This knob replaced the old plastic one on my tube amp perfectly. The aluminum feels premium and the knurling provides excellent grip. The set screw holds it tight without slipping.

Solid upgrade

Immediately noticed the difference in feel when adjusting volume during live sets. No more accidental slips. The indicator line is subtle but visible under stage lights.

Great quality, slightly tall

The build quality is outstanding for the price. It looks very sleek on my guitar. Just note that at 15mm height, it is slightly taller than standard stock knobs, but I actually prefer the leverage.

Good value

Nice heavy feel to it. Doesn't look cheap like the plastic ones. Took off one star only because the set screw was a bit hard to tighten in the small slot, but once done, it's secure.

5 FAQ

Q: Does the package include an Allen wrench?

A: Yes, each package includes a small Allen key specifically sized for the set screw, so you have everything needed for installation right out of the box.

Q: Will this fit a push-on shaft or does it require a set screw?

A: This knob is designed primarily for split shafts using the included set screw, but it can also function as a push-on knob for smooth shafts if the friction fit is sufficient. We recommend using the set screw for maximum security.

Q: Can I use this on a bass guitar?

A: Yes, absolutely. As long as your bass guitar uses standard 1/4 inch potentiometer shafts, this knob will fit and function correctly.

Q: What is the inner diameter of the hole?

A: The inner diameter is standardized at 6.35mm (1/4 inch), which fits the vast majority of guitar potentiometers and audio equipment shafts.

Q: Is the indicator line painted or etched?

A: The silver indicator line is laser-etched into the aluminum and then filled, ensuring it will not wear off over time with regular use.
