Tremolo or vibrato devices are well-known in the prior art. Tremolo devices are used in connection with guitars and similar musical instruments. Such devices serve to allow the player of a musical instrument to alter the tension of the strings of the musical instrument, thereby changing the pitch of the tone or sound produced by the strings.
Examples of prior art tremolo devices may be found in various patents, such as, Fender U.S. Pat. No. 2,741,146; Rose U.S. Pat. No. 4,171,661; Rose U.S. Pat. No. 4,497,236 and Storey U.S. Pat. No. 4,457,201. In each of these devices a lever having a single arm is manipulated in a vertical direction in order to operate the device and alter the tension on the strings and raise the pitch of the notes produced by the instrument. For many users, the configuration of the current lever is less than desirable.
