ABSTRACT:
A tremolo mechanism for varying the pitch of the strings of a musical instrument to create a vibrato effect includes a plurality of separately adjustable bridge segments, one for each string, which are mounted onto a pivotable plate and adjustable longitudinally to vary tension and hence frequency of a string, vertically to adjust the height of a string above the instrument, and laterally to align the strings horizontally with the instrument body.
