ABSTRACT:
A tremolo device for a guitar includes an upper plate pivotably mounted about a first fulcrum on a guitar body, at least one spring urging the upper plate in one rotating direction, a part of the guitar body coming into contact with the upper plate to limit the rotation thereof in the one rotating direction, to bring the upper plate to a predetermined position, and a lower plate pivotably mounted about a second fulcrum and pulled in another direction opposite to the one direction by the tension of strings of the guitar. The rotation of the lower plate is limited by the upper plate in the predetermined position when the tremolo device is inactivated, and when the tremolo device is activated in such a manner that the lower plate is rotated in the other direction, the upper and lower plates are rotated together, but when the tremolo device is activated in such a manner that the lower plate is rotated inthe one direction, only the lower plate is rotated.
