Abstract
A bi-directional vibrato mechanism for use with a stringed musical instrument is capable of being mounted to an instrument body without the need for providing additional holes or recesses in the instrument body for receiving portions of the mechanism. A front part of the mechanism is attachable to the guitar by two mounting posts and includes bridge type support members for the strings. A rear part is pivotally supported on the front part and anchors the lower ends of the strings. Two sets of springs located entirely above the top surface of the instrument body resiliently resist pivotal movement of the rear part relative to the front part in both pivotal directions away from a normal tuned position.
