ABSTRACT:
An improved fulcrum tremolo is disclosed, characterized by a unique mounting system and a novel adjustable bridge and fine turning assembly. A pair of screws having a blade-like heads are connected with the body of a musical instrument. The tremolo is arranged in a recess in the body of the instrument and includes in its forward edge tapered recesses to receive the screw head edges for pivotal movement thereabout. An adjustable bridge and fine turning assembly for the instrument strings is connected with the tremolo. For each string there is provided a body portion having a pair of rollers for supporting the string, and a tubular member for receiving the string. The tubular member is arranged in a recess within the tremolo. Harmonic tuning is adjusted by sliding the body portion and tube within its recess longitudinally, essentially without altering the tuning of the string. A string securing member is connected with the tremolo to vary the tension of each string. Each string securing member includes a thumbscrew for rotating the member relative to the tremolo to individually adjust the tension of each string, the thumbscrews being vertically offset to provide a low profile tremolo.
