This is purely by accident. All I wanted was to use a sustain pedal and my improvised splitter was playing up so I bought a splitter converter online which is 3.5mm stereo to 1/4 inch female socket jack. And when it arrived, I tried it and it converted the pedal into double bass pedal.
Here's my other video on the sustain pedal in case you are interested in getting a cheap but durable sustain pedal which can be used as your drum pedals.
