Abstract: A tremolo assembly for a stringed instrument such as a guitar can be used in an instrument comprising a body, a neck and a head. Strings are strung between the head and the tremolo assembly. The tremolo assembly comprises a base plate which is mounted to the body and a tone block which is pivotally attached to the base plate and extends into a cavity in the body. Saddles are attached to a top of the base plate in front of the tone block. The strings are strung over both the saddles and the tone block, and attached to the tone block near a bottom thereof. One or more tone block springs are attached between a lower portion of the tone block and the body. A tension bar is held against the back of a lower portion of the tone block by at least one tension bar spring when the tone block is in a neutral position. Stopping means are provided to prevent the tension bar from urging the tone block forward of the neutral position.

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.
