## CPC

- G10D 3/153: Tremolo devices
- G10D: STRINGED MUSICAL INSTRUMENTS; WIND MUSICAL INSTRUMENTS; ACCORDIONS OR CONCERTINAS; PERCUSSION MUSICAL INSTRUMENTS; AEOLIAN HARPS; SINGING-FLAME MUSICAL INSTRUMENTS; MUSICAL INSTRUMENTS NOT OTHERWISE PROVIDED FOR (organs, harmoniums or similar wind musical instruments with associated blowing apparatus G10B; pianos, harpsichords, spinets or similar stringed musical instruments with one or more keyboards G10C; automatic musical instruments G10F; electrophonic musical instruments in which tones are generated by electromechanical means G10H)

## Abstract

This tremolo device includes a flat hand plate and a short mounting post welded perpendicularly to bottom of the hand plate. The hand plate is configured and bent to form a curved eminence and depression along one side, which provides additional structural integrity and rigidity to the tremolo device. The mounting post is adapted to rotatably connect to the bridge assembly of a stringed instrument. The mounting post elevates the hand plate over the bridge assembly and instrument strings. The musician can rest the palm of the picking hand on the top of the hand plate, which positions the fingers conveniently over the instrument's strings. The musician can push or pull on the hand plate to apply force to the bridge and change the tension of instrument's strings.

## Claims

### Claim 1

A tremolo device for stringed instruments having an instrument body, a plurality of strings extending thereover, and a bridge assembly connecting the plurality of strings to the instrument body and capable of limited pivotal movement relative to the instrument body,
the tremolo device comprising:
a substantially planar hand plate: and
a post extending perpendicularly from the hand plate, the post adapted for mounting to the bridge assembly so that the hand plate is spaced over the bridge assembly and strings and so that the post rotates axially relative to the bridge assembly,
the hand plate has a top surface and a bottom surface, the hand plate also having an elongated eminence rising from the top surface and a corresponding elongated depression descending from the bottom surface.

### Claim 2 (depends on 1)

The tremolo device of claim 1 wherein the hand plate has an ovate shape.
