ABSTRACT:
A tremolo device with a movable bridge, an adjustment device, and a support frame is implemented on an acoustic guitar, with features that can also be employed on an electric guitar or other stringed instruments. The movable bridge holds strings of the musical instrument in tension. The adjustment device, such as a tremolo bar, moves the bridge to change the tension of the strings. The support frame engages the bridge at a first area and engages the musical instrument at a larger second area. When the tremolo device is used, the support frame receives a force over the first area and transmits a corresponding force to the musical instrument over the larger second area, reducing the pressure that would be experienced by the musical instrument. The support frame also transmits string vibration received through the bridge to the instrument body to produce proper acoustic tones.
