Mu-Tron Knob

thingiverse

Replacement knob for restoring your 1970's Musitronics/Mu-Tron effects pedal. You can't get these anywhere. Fits the splined shaft they used. On mine I did a color change to black on the last layer of the top face, and then changed back. It looks nice with micro layers, or a .25mm nozzle, if you have the patience. Printed with supports. Free for private or commercial use, have fun!
