An improved tremolo mechanism for a guitar. The tremolo mechanism for a guitar includes a rotary assembly. The rotary assembly includes a main rotor that includes an arcuate shaped surface defining holes through which a plurality of guitar strings exit the main rotor when the tremolo mechanism is installed on a guitar, resilient means coupled to said main rotor to bias said rotary assembly to a first position at which no tremolo effect is provided and away from a second position at which a tremolo effect is provided and fixing means on the main rotor for securing one end of each of the plurality of guitar strings to the rotary assembly. The tremolo mechanism also includes a plurality of tension rollers for providing rotational tension to said guitar strings. Said arcuate shaped surface directionally guides said strings transverse of said rotary assembly to the tension rollers.
