ABSTRACT:
A device for continuous pitch variation of a stringed musial instrument. The neck portion of the instrument is movable relative to the body, to vary the tension on the strings, thereby to vary the pitch during playing. Locking means is provided for locking these parts against movement when no variation in pitch is desired, and for quickly unlocking the parts to allow movement when the variation is desired. The locking arrangement is responsive to pressure exerted by the playing arm of the player, exerted on a control member on the body of the instrument. Locking is accomplished by driving a rotary locking wheel into a tapered locking notch. There is provision for maintaining the lock in an effective locking position when no movement would be desired, as for example during transportation of the instrument.
