MXR Pitch-shifter doubler rack unit

What was the intended use for this thing? It sounds like a chorus with a selectable ramp/saw LFO wave. Took one in on trade just because it was weird and apparently kinda rare. If I can track down a schematic I just might turn it into a "proper" chorus with some changes to the LFO circuitry.

Aahh....after even more digging it appears this was some variation on the "barber pole" phase concept. Thats why the LFO wave is ramp/saw. So the 2 outputs should be 180* out of phase. I'll hafta see what it does in stereo before I go screwing with it.....
