Hey thanks man, @SubApathy nailed it. I bought it new from AM with the mods. It's a '74 reissue phase 90 and has the following mods: external mix knob, internal volume trimmer, orange LED, true bypass, and 9v jack. So it's the awesomeness of the 74 reissue with none of the drawbacks IMO. The mix knob makes it like a phase 45 but I'd probably leave that out if I ordered again.
