32mm black anodized aluminum knob, 14mm tall, straight knurl.
Machined from aluminum alloy #6061 and with a depth of 12.5mm the skirt covers the pot's bushing and retains clean, sleek aesthetic for your pedal. Great for using your toe to adjust settings on the fly, too. Last 2 pictures show the size comparison with 20mm knob.
