ABSTRACT:
The invention is a tremolo device for adjusting the string tension in a stringed musical instrument including a body having an upper surface, a neck portion, a tuning head having a series of tuning devices, a multiplicity of strings each anchored at a first end to a respective one of the tuning devices and extending over at least a portion of the neck portion and the body. The tremolo device includes a base plate attached to the body of the instrument and a movable plate having first and second edges extending in a direction perpendicular to the strings. The movable plate is mounted to the base plate along the second edge of the movable plate about a pivot axis and in a horizontal position with its longitudinal axis perpendicular to the strings. The first edge of the movable plate is adapted to securely anchor the second end of each of the strings. The tuning devices are manually operable to stretch the associated strings between itself and the movable plate to apply a preselected tension force to each of the strings which bias the movable plate in a first direction of rotation about the pivot axis. A biasing member is connected between the base plate and the movable plate for biasing the movable plate about the pivot axis in a second direction of rotation opposite the first direction. An actuating arm is attached to the movable plate to allow rotation of the movable plate in one of the first and second directions of rotation to adjust the tension of the strings.
