FS: 1975 MXR Phase 90, vintage!
Fantastic pedal here. Purchased by my father and handed down to me, however I've not done more than just play around with it. So I guess you could say it's a single-owner pedal.
The pot code dates it to 1975. All wear and tear is 100% natural (and looks really cool). The only thing on the negative side is it is missing one of the four bottom screws. I'm still looking around for it, as I know it's got to be around my music room somewhere.
$250 shipped. Pics to come.
