Abstract
A tremolo block extends from the back of a base plate into a space formed in a body. The tremolo block pivots with the base plate. The tremolo block has a hook portion at its distal end. The base is located at the back of the body. Engaging sections are formed at a rear portion of the base and open rearward. A moving member is detachably located at the engaging sections. The moving member is moved between an engaging position, at which the moving member engages with the engaging sections, and a standby position, at which the moving member is separated from the engaging sections. A pair of first springs connect the base with the tremolo block to urge the tremolo block forward against the tension of the strings. The urging force of the first springs is adjustable. A pair of second spring connect the base with the moving member. The second springs urge the moving member toward the engaging position. In a normal state, the second springs hold the moving member at the engaging position. When the tremolo block is stopped or pivoted forward, the moving member is held at the engaging position by the urging force of the second springs. When the tremolo block is pivoted rearward, the moving member is moved from the engaging position to the standby position by contact between the moving member and the hook portion.
