ABSTRACT:
An improved device for tuning a string of a musical instrument includes a string post which is axially movable relative to a housing. A clamp assembly inside the string post grips a portion of the string. The string post is then moved axially to tension the string. A single tuning knob is utilized to perform the dual functions of actuating the clamp assembly to grip the string and moving the string post axially to tension the gripped string. When the tuning knob is in an extended position, a socket type clutch interconnects the tuning knob and a clamp screw. Rotation of the extended tuning knob rotates the clamp screw to grip the string. When the tuning knob is in a retracted position, the clutch between the tuning knob and the clamp screw is disengaged and a drive connection between the tuning knob and the string post is engaged. Rotation of the retracted tuning knob causes the drive connection to move the string post axially to tension the string.
