Abstract
A stringed instrument, such as a guitar, has a vibrato that includes a bridge rotatably mounted within a body of the instrument. A flat compression spring extends from the bridge to a position away from a neck of the instrument. At the other end, the spring abuts a support that is linearly movable relatrive to the bridge to increase or decrease the compression force of the spring. A step stop is positioned near the bridge to allow a user to selectively move the bridge between a floating mode in which it can rotate in either direction from a neutral position to a classic mode in which it can move in one direction. The compression can be adjusted so that the bridge is effectively stopped from moving in a direction opposite to the particular direction. The bridge is moved with a control bar that extends into a rotatable bushing. The frictional forces between the bushing and the bridge can be adjusted with a set screw. The bar has a generally hexagonal cross section and is bowed within the bushing so that it can be easily removed and reinserted if desired.
