This is a project to clone the original EHX Polyphase. None of that fancy stereo output crap, none of that start and stop of the sweep nonsense; pure analog envelope controlled LFO optical phasing! Simply one of my favourite phasers of all time. And no, it wont fit in a 1590BB sized enclosure.
Original unit
When I drew up this project I worked from an old factory Schematic of both the polyphase and deluxe phaser. I have yet to draw a schematic into the project file, well, because I haven't found the time. The PCB is verified and working. If you dont think you can build it, you probably can't.
