Solid plastic construction

Don't let the 'plastic' description fool you; this is high-grade material. They don't feel cheap at all. The textured surface makes adjusting volume during live performance very easy.

Perfect fit for my Stratocaster

These knobs fit perfectly on my guitar's potentiometers. The grip is excellent, and the matte black finish matches my hardware beautifully. Very happy with this purchase.

Works well for DIY pedals

Bought these for a custom pedal build. They fit the shafts tightly without needing extra set screws. Only wish they came in more colors, but the quality is there.

Exactly as described

Fast shipping and the product matches the description perfectly. The dimensions are accurate, and they sit flush against the guitar body. Highly recommended for replacements.

Great for amp restoration

I used these to replace worn-out knobs on a vintage tube amp. The 15x10mm size is spot on for standard audio pots. They feel sturdy and look professional.

Good value, slight color variation

Functionally these are great and easy to install. The black is slightly lighter than my existing pickups, but not enough to be a dealbreaker. Good size for precise control.

5 FAQ

Q: Do these come with set screws included?

A: No, these are push-on style knobs. If your application requires set screws, you may need to source them separately or drill and tap the side if you have the appropriate tools.

Q: What is the inner diameter of the hole?

A: The inner diameter is approximately 6mm, which is the industry standard for most guitar and audio equipment potentiometers.

Q: Will these fit a solid shaft potentiometer?

A: These knobs are primarily designed for split shafts (D-shafts). While they can be forced onto a solid shaft, we recommend using a small set screw or adhesive for a secure fit on solid shafts.

Q: Can these withstand high heat from tube amps?

A: Yes, the ABS plastic used is heat resistant enough for standard amplifier chassis temperatures. However, direct contact with vacuum tubes should be avoided.

Q: Is the black finish glossy or matte?

A: The finish is a smooth matte black, designed to reduce glare on stage and resist showing fingerprints.
