If you are a perfectionist about your knobs, a nerd about your gear, the kind of person who can obsess over the exact shade and texture of matte black aluminum . . . this is your knob.

The unique matte black finish on the Sandblasted Black Aluminum Knob offers a subtle texture, providing extra grip that can be especially useful when making adjustments in tight proximity to other knobs.

The knob fits smoothly on a 18T knurled shaft potentiometer--for pedals, pro-audio gear, and modular synths.

Available in two outer diameters:

Small - 10.2mm

Medium - 12.7mm
