ABSTRACT:
A stringed instrument tuning device is disclosed that is enhanced over the prior art by an included mechanism that enables the tuning knob to be positioned freely in any rotational position after a string has been tensioned or tuned. A worm gear drive tuning assembly typical of prior art tuning devices is employed. In one approach, the tuning device includes a common ratchet mechanism that enables free rotation of the tuning knob with respect to the tuning mechanism. In other embodiments disclosed, a spline shaft engagement mechanism is employed with a shuttle that releasably engages the tuning knob to the worm gear drive tuning assembly.
