One of the goals of this entire build was to have all the smaller drums and cymbals and hardware pack up into the bass drum for transport. In addition, to simplify the kit setup and to make the footprint smaller, I wanted to use the bass drum as the player’s stool. So the bass drum had to be basically a large, strong, square box with one side as the resonating skin. They don’t make file folders large enough for this, so I simplified and tried a thin piece of MDF to start with.
There is a South American instrument called a cajon which is basically the same thing I was thinking, except a cajon is usually sealed on all sides (except for a sound hole) and played with the hands. I wanted to have a traditional kick drum pedal happening, so I needed to find a way to make a pedal with a remote beater that faced backwards.
