Aluminum Skirt knob for Mystery Brain, pack of 7
for 1/4" solid shaft, w/ set screw. (the skirt on these knobs hangs slightly over text below each control pot) NOTE: These NOS are brushed alum and some scratches on them cannot be helped. I am not a knob supply store, I just allocated a bulk shipment of these and what I get is what I get. They are fully functional.
