PURPOSE: To make it possible to rapidly change an effect set value even during playing by mounting a treadle pendulum plate at an effect adjusting function section. CONSTITUTION: This mechanism is composed of a variable resistor 11 for adjusting special effects mounted on the front and rear of a special effect device body 1 and the pendulum plate 7 provided with an antislip rubber plate 2, 'Teflon (R)' rubber 8, a hole for mounting a shaft and a hole for tightening the shaft. The pendulum plate 7 is mounted at the shaft part 12 of the variable resistor 11. The pendulum plate 7 and the shaft 12 are fixed by a screw 15 for tightening the shaft. In such a case, a user places the foot on the antislip rubber 2 disposed on the front surface of the pendulum plate 7 and moves the toe laterally, by which the pendulum plate 7 is eventually rotated laterally around the variable resistor 11 as a fulcrum. This rotation is interlocked to the shaft part 12 mounted at the pendulum plate 7 and eventually the resistance value of the variable resistor 11 is changed. |
