ABSTRACT:
The invention is an electric guitar that has seven strings and a scale length of 25.5 inches. The highest string is a "top A" string that provides the guitarist access to higher notes than is available on a conventional guitar. This seven string guitar is constructed on a solid body and has a neck with twenty-four frets. The neck has "pronounced tapering" such that the proportionate relationship of the neck at the 24th fret and at the nut is greater in the present relationship than in the Fender Stratocaster guitar. The solid body has cut-aways on each side of the neck to permit fingering access to all the frets. The guitar has staggered headmachines so that the headmachine upon which the "top A" string is wound has a shorter post than those headmachines upon which the lower strings are wound. The guitar also has a vibrato bridge unit that is firmly connected to the solid body by two connecting screws and less than firmly attached to the solid body by two stabilizing screws. The vibrato bridge unit further has saddles mounted at maximum height to increase the sustain on the sounds generated by the guitar. A shim is placed between the neck and solid body to tilt the neck backwards to offset the raising of the strings by the raised saddles.
