There is a big difference between the distance and force of the pedal depression and rebound, and one foot deep and one foot shallow makes people feel unsafe; 2. The traditional direct drive connecting pedal driving method: stepping on the pedal drives the lower rod at the front end of the pedal downward. Pull, with the downward pulling force as the transmission, the pull rod pulls the upper pull rod to drive the hammer rod seat on the right front axle to move forward, so that the hammer head hits the drum surface, and when the foot leaves, the tension spring pulled by the shaft contracts and moves backward, making the hammer Head off the drumhead. Although the chain pedal in this traditional pedal is easy to control, the force is weak and the muscles cannot be tensed when playing fast; the direct drive pedal is fast but the rebound becomes unstable, which drives the muscles to tighten against the rebound force. People's strong desire for control and the instability of the pedal make it difficult to practice and increase the practice time; 3. The shape of the traditional pedal is wide in the middle, and the board surface is flat, which is not conducive to force; 4. The sound of hitting: the traditional pedal hits The sound was dull and opaque. Faced with different brands of kick drums, it may take a lot of time to adjust the pedals and kick drums to meet the timbre needs of the musicians; 5. Carrying and space: Traditional pedals take up a lot of space and are heavy to carry.
