The Homebrew Electronics Big D is an analog overdrive and distortion pedal. RockBoard's PedalPedia describes it as "an extremely versatile overdrive/distortion capable of achieving many different sounds ranging from light bluesy overdrive to modified hi-gain tube amp distortion"1. That range puts it across the territory of both overdrive pedals and distortion pedals, depending on how far the gain is pushed.
What it does
The Big D covers a wide gain range in one box. At the low end it produces light, bluesy overdrive; pushed further it reaches a modified hi-gain tube amp style distortion1. For a player, that means one pedal can serve as a clean boost style push for a tube amp and as a standalone distortion source, rather than needing separate overdrive and distortion units on the board.
Power and circuit
The Big D is an analog circuit and runs on 9V DC, center negative1, the standard pedal power arrangement used by most supplies and daisy chains.
