Claim:
A tremolo unit for an electric guitar, wherein support members are located on the body of the guitar, and strings are supported by the support members at predetermined positions along a longitudinal direction, of the guitar body, fine-tuning means and harmonic tuning means for tuning the strings, the tremolo unit comprising: a base plate, a plurality of saddle holders located on the base plate, the base plate is pivotally supported on the guitar body, and a position of each saddle holder can be adjusted in a longitudinal direction of the strings; a plurality of saddles, each saddle is rotatably coupled to one of the saddle holders and corresponds to one of the strings, each saddle is shaped to contact the corresponding string at a predetermined point along the length of the base plate regardless of the pivot orientation of the saddle; a plurality of string holders, each string holder is located in one of the saddles, a part of each string holder holds the corresponding string and the part that holds the string is below the contact point of the string on the saddle; the saddle is biased vertically and in direct contact with the fine-tuning means and the fine-tuning means is vertically movable to fine-tune each string by changing the rotational angle of the corresponding saddle without actually changing the contact point of the corresponding string on the saddle; the harmonic tuning means is movable along the longitudinal direction of the strings to adjust the position of each saddle holder on the base plate in the longitudinal direction of the strings; and a manipulation portion located on the harmonic tuning means, the manipulation portion tunes the harmonic of each string at a position above the base plate while the string is held by the associated string holder.
