There’s nothing like the lush, thick phasey tones of the original MXR Phase 90s. The circuit is so simple that it’s hard to believe the reissues don’t even come close. This ~1980 MXR Phase 90 (pot code 1378041, so 41st week of 1980) is in very good condition and works like it should. It includes the original box, which is pretty weathered as shown in the photos. Please call (970) 728-9592 or e-mail for an in-hand description.
