Various embodiments of the present invention are directed to an enhanced knob with multiple integrated functions for use with an electric stringed musical instrument. The enhanced knob can be positioned on an electric stringed musical instrument or on an interconnected amplifier and can be either an add-on feature or can replace one or more existing knobs. In one embodiment of the present invention, the volume knob for an electric guitar is removed and replaced by an enhanced knob. The enhanced knob includes a switch that allows a user to switch between the multiple functions and also allows the user to control each selected function. The enhanced knob includes a volume function to compensate for the removed volume knob. Additionally, the enhanced knob includes a number of other functions, including a tuner function, a metronome function, and a dynamic visual-display function.
