Abstract

A tremolo for a multiple stringed musical instrument such as guitar is provided having independently movable plates each of which support one or more guitar strings. A sliding clip may be provided which engages adjacent plates and may be used to selectively provide a tremolo effect simultaneously on all of the strings of the instrument or on a portion of the strings. A tremolo arm is provided for each plate so that when the plates are disengaged, each plate may be independently operated to produce a tremolo effect on a portion of the strings of the instrument. A spring operated tremolo return apparatus is provided for maintaining the tremolo in a neutral position. Saddles which engage with the plates of the tremolo are provided which facilitate rapid string changes.

Claims

1. A tremolo for a multiple stringed musical instrument comprising a plurality of independently movable string support plates, each string support plate having means for attachment of a tremolo arm to the plate and hinge means for pivotal connection of the plate to a body of the musical instrument, wherein said hinge means comprises a hinge element common to each of the string support plates and extending from a first side of the tremolo to a second side of the tremolo and for supporting the string support plates on an instrument body.

2. The tremolo of claim 1, having locking means engageable between each adjacent string support plate to transmit pivotal movement from one plate to an adjacent plate.

3. The tremolo of claim 2, wherein each string support plate additionally comprises bridge means for supporting one or more instrument strings on the string support plate and retaining means for fixation of each of said strings to the tremolo.

4. The tremolo of claim 1 having two string support plates.

5. The tremolo of claim 4 in combination with a guitar wherein each string support plate comprises bridge means and retaining means for at least three guitar strings.

6. The tremolo of claim 1, wherein the common hinge element is a pin having ends engaged in one or more brackets at one or both of the first and second sides of the tremolo.

7. A tremolo for a multiple stringed musical instrument comprising a plurality of independently movable string support plates, each string support plate having means for attachment of a tremolo arm to the plate and means for pivotal connection of the plate to a body of the musical instrument, wherein each string support plate has a tremolo lever extending from a lower surface of the plate, each tremolo lever being configured to be connected by resilient means to an instrument body, and wherein the tremolo includes a supporting bracket between adjacent string support plates extending in the direction of the tremolo lever, the supporting bracket being mountable within a cavity in the instrument body.

8. The tremolo of claim 7, wherein the resilient means is a spring engageable in a hole in a side of the lever away from the plate.

9. The tremolo of claim 7, wherein the supporting bracket includes one or more compression springs and guide means for each spring, wherein each spring is configured to urge a tremolo lever to a neutral position.

10. The tremolo of claim 9, in combination with a guitar having a cavity configured to receive each tremolo lever and the supporting bracket, wherein the tremolo has two string support plates, each support plate comprising bridge means for supporting three adjacent guitar strings and retaining means for fixation of each string to the tremolo and wherein each tremolo lever is connected to a wall of the cavity by a spring under tension to urge the lever towards the wall of the cavity, and wherein each compression spring on the supporting bracket is configured to urge the lever away from the wall.

11. A tremolo for a multiple stringed musical instrument comprising a plurality of movable string support plates, each string support plate having means for attachment of a tremolo arm to the plate and hinge means for pivotal connection of the plates to a body of the musical instrument, wherein said hinge means comprises a hinge element common to each of the string support plates and extending from a first side of the tremolo to a second side of the tremolo and for supporting the string support plates on an instrument body, and wherein each string support plate has a tremolo lever extending from a lower surface of the plate, each tremolo lever being configured to be connected by resilient means to an instrument body, and wherein the tremolo further including a supporting bracket between adjacent string support plates extending in the direction of the tremolo lever, the supporting bracket being mountable within a cavity in the instrument body.
