PURPOSE: To accurately restore an arm to a normal tuning state after arm operation and to maintain an accurate musical interval by independently forming respective supporting points for a sharp and a flat and increasing the tension of a spring or string. CONSTITUTION: When an arm 11 is depressed to flat an interval, the whole tremolo device 1 is rotated around a screw 5 to be a supporting point in the counterclockwise direction, the tension of a string 7 is loosened and the interval is turned to flat. In the case of sharping the interval, a lower plate 3 is rotated around a screw 6 to be a supporting point in the clockwise direction, the tension of the string 7 is increased and the inverval is turned to sharp. When a hand is removed from the arm 11 after the tremolo operation, the arm 11 is accurately restored to a normal tuning position and a normal playing state is held. |
