PROBLEM TO BE SOLVED: To adjust a pedal to a state wherein it is easy for a player to step on by detecting the stepping-on manipulated variable of the pedal that is turned and supported slantingly to a bottom plate and energized upward and adjusting the upper turning limit position of and the operation load on the pedal. SOLUTION: The pedal 2 is turned and supported slantingly to the bottom plate 1 and energized upward by a compression coil spring 9. The compression quantity of the compression coil spring 9 is varied by turning a wingnut 8 and the operation load on the pedal 2 can be adjusted. Further, when the pedal is stepped on, a plate 5a at the lower end of a shaft 5 presses sensor rubber 3 and the electric resistance of a sensor pattern 4 varies. The variation is detected by a musical sound production part and a hi-hat cymbals sound of a timbre corresponding to the stepping-on quantity is sounded. Further, an initial angle adjusting bolt 7 is turned to vary its height (h), and then the height H of the pedal 2 is adjusted. Further, the level of the detection signal of the sensor pattern 4 corresponding to the stepping-on quantity of the pedal 2 can be adjusted by varying the lower-end length L of the shaft 5. |
