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.

Tremolo device for a guitar

A tremolo device for an electric guitar comprises a movable block, to which the strings are anchored, which is swingable about a swing axis perpendicular to the strings. The block has counter balance tensile springs for providing a tension on all of the strings, whereby an equilibrium is established between the tension imposed by the counter balance tensile springs and the tension imposed on all of the strings, whereby the block is kept at a neutral position. A tremolo handle is rotatably attached to the block, and is rotatable between an operative position at which the handle can be manually operated by a player, to produce a movement of the block about the swing axis and change the tension imposed on all of the strings, and an inoperative position at which the handle cannot be accidentally touched by the player. The device comprises a lock mechanism for locking the block at the neutral position at a middle location thereof, and the lock mechanism is actuated by rotating the handle from the operative position to the inoperative position.
