From the vendor
The 8-Bitar prototype, AKA the BitBreaker.
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.
The design goal with this pedal was to achieve a square wave octave down with as few components as possible. I'm happy with the result since it only uses one chip (a CD4069) and one transistor.
Usual caveats apply for getting the best tracking - humbuckers, neck pickup and tone rolled off.
