Abstract
The tremolo apparatus of the present invention includes a tremolo means (13) with a tremolo bar (19) and a base flange (23) which extends into a cavity (21) in the guitar (11). When the tremolo means is operated conventionally, springs (25) return the tremolo means (13) to an original position against a stop (37) located in the cavity (21). Stop (37) is mounted for movement on rods (42 and 44) against the action of springs (47 and 49). When the tremolo bar (19) is moved toward the body of the instrument, such as a guitar, the tremolo means (13) moves in a first direction wherein the base flange (23) moves away from stop (37), while when the tremolo bar (19) is moved away from the body of the guitar, the tremolo means moves in a second direction wherein the base flange (23) moves stop (37) against the action of springs (47 and 49). Springs (47 and 49) return stop (37) and the base flange (23) and hence the tremolo means (13) to their original position when the tremolo bar is released.
