The 8-Bitar is a minimalistic octave down pedal with a 8-bit sound (glitchy and gated square wave fuzz). It's small enough to fit inside a 1590A without any special parts.
The design goal with this pedal was to achieve the core octave tone from the Arcadiator, but with as few components as possible. I'm happy with the result since it only uses one chip (a CD4069).
Usual caveats apply for getting the best tracking - humbuckers, neck pickup and tone rolled off.
