Abstract: A mechanism to prevent a knob from being moved accidentally. An inner hub is held in place on the adjustable shaft. An knob body fits concentrically over the inner hub, and is biased into position over the hub. The bottom of the barrel has locking structure which lockingly but releasingly cooperates with locking structure associated with the piece of equipment (e.g. musical instrument or amplifier) to which the shaft is affixed.
