• a plurality of tremolo mechanisms corresponding to the plurality of strings attached to the end of the plurality of strings attached to the body, the plurality of tremolo mechanisms each comprising a mount which receives an end of one of the plurality of strings, a pivot mounted to the body, a short pivot arm extending rearwardly the one of the plurality of strings, a tremolo arm which extends upwardly and then forwardly from the short pivot arm and a compression spring which extends downwardly and forwardly from the distal end of the short pivot arm and is mounted on the interior of the body for resiliently biasing the tremolo mechanism to a selected position,
• a fret board mounted on the neck, the fret board having a plurality of frets thereon, and
• a plurality of female receptacles positioned on one of the fret board and the neck mating with a corresponding number of male receptacles positioned on the other of the fret board and the neck, the male and female receptacles are a combination of a box shape with a contiguous right triangle shape, and a snap for retaining the fret board on the neck.
