ABSTRACT:
A combined bridge and tailpiece assembly for a stringed musical instrument such as a guitar is disclosed, characterized by a tailpiece member which is manually rotated to produce a vibrato effect. The assembly includes a tailpiece block which is secured to the body portion of the instrument and an elongate tailpiece member rotatably connected at its ends with the tailpiece block for rotation in one direction about an axis parallel with and eccentrically horizontally and vertically offset from the longitudinal axis of the tailpiece member to provide camming action. Adjustable string attachment devices are connected with the tailpiece member for attachment to the ends of the instrument strings which, when tensioned, normally bias the tailpiece member in one direction of rotation. A plurality of adjustable saddle rollers are connected with the tailpiece block and act as a bridge to guide the instrument strings to the string attachment devices. The tailpiece member is spring biased in the other direction of rotation to resist the rotating force exerted on the tailpiece member by the tensioned strings, and at least one lever is connected with the tailpiece member for rotating the same relative to the tailpiece block during sounding of the instrument to produce a vibrato effect.
