Looks great on custom pedals

Adds a very professional look to my custom guitar pedals. The 40mm size is substantial without being too large.

Good value, slight color variation

Works exactly as described. The silver finish is slightly darker than in the photos, but it still looks professional on my control panel.

Excellent grip texture

The knurled mesh design makes it very easy to turn even with sweaty hands. Highly recommended for volume controls.

Perfect fit for my amplifier project

The build quality is excellent. The mesh texture provides a great grip, and the splined shaft fits my potentiometers perfectly without any wobble.

Solid component

Good quality aluminum. Just make sure to check your shaft diameter; it is designed specifically for splined shafts, not smooth round ones.

Sturdy and precise

I bought ten of these for a modular synth build. They are heavy, feel premium, and the set screw holds tight even after frequent adjustments.

5 FAQ

Q: Will this knob fit a standard 6mm smooth round shaft?

A: No, this knob is designed specifically for splined shafts. It will not securely fit a smooth round shaft without an adapter.

Q: Does the package include the set screw?

A: Yes, each knob comes with one small set screw required for securing it to the shaft.

Q: Is the 13mm height including the base or just the grip part?

A: The 13mm measurement refers to the total height of the knob from the bottom of the base to the top of the cap.

Q: Can I paint or anodize this knob myself?

A: Since it is raw aluminum, it can be anodized or painted, but please note that doing so may void any return policy if damaged during the process.

Q: What is the inner diameter of the splined hole?

A: The inner diameter is designed to fit standard 6mm splined shafts commonly used in audio potentiometers.
