Abstract
A control knob for controlling an underlying signal is disclosed. The control knob includes a clear radial portion which serves as an indicator on the knob. The radial portion receives light from a multi-color LED which is housed within a clear shaft of a potentiometer which rotates in concert with the control knob and controls the level of the underlying signal. The multi-color LED emits light of a color which is dependent upon the level of the underlying signal being controlled by the control knob.
