Hacks and tricks to improve the foot pedal or bass drum kick of this Roll Up DrumKit

Found a hack or trick to change the foot pedals of this roll up electronic drumkit. I bought a Y splitter which was 3.5mm male to stereo 1/4 female jack. Then I used my old sustain pedal and my son's Rock Band 3 foot pedal for the drums to improve the kick of the bass drum as well as the hi-hat of this roll up drumkit.
