Abstract
A tremolo mechanism for a guitar provides a tremolo effect. The mechanism is provided with a device against which the strings are pressed, and which is rotatable round a rotary shaft located between the bridge and the string-fixing part of the guitar, the device being capable of changing the tension, in each string by rotating about the rotary shaft and thereby changing the distance from the axis of the rotary shaft to the point at which each string presses against the device.
Claims23
A tremolo mechanism for a guitar comprising:
- a main rotor;
- means supporting said main rotor for rotational movement relative to a guitar about a rotational axis extending generally tansverse to a set of strings on the guitar and generally parallel to a surface of the guitar over which said strings extend;
- resilient means coupled to said main rotor to bias said main rotor to a first position at which no tremolo effect is provided and away from a second position at which a tremolo effect is provided;
- a fixing means on the main rotor for securing one end of each of said strings to the main rotor;
- tension adjustment means for individually varying the degree of tension to a different extent for each of said strings as said main rotor is rotated between its said first and second positions, the tension adjustment means being coupled to the main rotor for rotation therewith.
