The Doof Doof machine comprises of one of Eric Archer’s delightful Mini Space Rockers, combined with a trusty oscillator and a bunch of knobs in order to make it an almost-convincing bass drum machine.
The unit is hooked up with a tempo adjustment pot and a doof speed divider in the form of a rotary switch. This provides the ability to have doofs on every beat, every second beat, fourth beat, etc.
There’s also a switch to toggle between regular and divider modes and a supplementary button to trigger regular mode. This allows for momentary doof freak-out, to keep things corny.
The Doof Doof machine also features a gate input and a gate input selector switch. The gate input allows the unit to be driven from an external sequencer.
