- a string instrument bridge which provides a connection for the strings of the instrument;
- an extension from said bridge which runs to the back of the string instrument;
- a bar capable of attaching to the bridge extension wherein the bar is designed in a "T" shape, the perpendicular portion of the "T" capable of attaching to the bridge extension;
- a pin affixed to the forward side of a guitar near the strings;
- a curved stop including a partial slot wherein the pin is capable of sliding within the slot, but the slot also confines its travel due to its striking either end of the slot;
- a means for attaching the curved slot to the bridge;
- a spring affixed to the housing of the instrument and the bridge whereby when the tension is released from the bar, the bridge returns to its previous position.
