Abstract
A tremolo device for a guitar includes a flat plate pivotably mounted relative to a guitar body, another plate secured on an under surface of the flat plate, a first fulcrum part of the flat plate for a pivotting thereof to lower a tone of the guitar, a second fulcrum part of another plate for a pivotting thereof to raise the tone of the guitar, and screws fitted to the guitar body and in contact with both fulcrum parts. When a tremolo arm is inactivated, the plates come into contact with the screws at both the first fulcrum part and the second fulcrum part, and when activating the tremolo arm, either one plate or another plate comes into contact with the screws and is rotated about either of the fulcrum parts.
