ABSTRACT:
An improved bridge for a guitar or other stringed instrument which offers individual height and length adjustment for each string. The bridge uses adjusters in which one part, the saddle, pivots or rocks, on a fulcrum relative to a supporting part, the anvil. The fulcrum may be incorporated into either part or may be a separate element. The fulcrum is generally perpendicular to the string and extends the full width of the adjuster. This configuration, combined with a close fit at the fulcrum results in a tight fit with minimal linear movement and no axial movement (about the vertical axis) between the parts of the adjuster. The combination of this with the ability to use relatively large elements results in an adjuster, and a bridge, with minimal dampening effect, or energy loss, on the string and improved transfer of sound energy to the sound board of the instrument.
