Good value for the price

Solid plastic construction. They look great on my amp. I took off one star because the black finish shows fingerprints easily, but otherwise excellent.

Decent but tight fit

The quality is fine, but the hole was slightly smaller than expected. I had to apply a bit of force to get them onto the shaft. Once on, they are secure though.

Great for DIY projects

Bought these for a custom bass build. They match the aesthetic perfectly and the height gives good leverage for precise control adjustments.

Sturdy and stylish

The textured surface provides a good grip for quick volume swells. They feel durable and look professional on my pedalboard setup.

Exactly what I needed

Replaced the cracked knob on my vintage tube amp. The 16x15mm size is standard and these slipped right on. Very happy with the purchase.

Perfect fit for my Stratocaster

These knobs fit perfectly on my guitar's potentiometers. The friction is just right, not too loose and not too tight. Great replacement for worn-out stock knobs.

5 FAQ

Q: How many knobs are included in one order?

A: Each order includes a pack of 2 identical knobs, which is usually enough to replace a volume and tone pair on a single instrument.

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 amplifier pots.

Q: Can these withstand high heat from tube amps?

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

Q: Do you sell these in white?

A: Currently, this specific 16x15mm model is only available in Matte Black. Please check our store for other sizes that might come in white.

Q: Will these fit a solid shaft potentiometer?

A: No, these knobs are designed specifically for split shaft (slotted) potentiometers. They may not stay secure on a solid smooth shaft without adhesive.
