Pre-owned 1979 MXR Phase 90 (block style).
In fair condition, but perfect playing condition. Shows wear from normal years of action. One of the screws are missing from the bottom case, and the existing three are non original. The battery connection cable has been extended for extra length.
This is the pedal you've heard on thousand of records and live. Classic tones in a simple format!
The Phase 90 was the first pedal sold by MXR and helped launch the company in 1974. The original model had a simple orange enclosure with a script style MXR logo. In 1977 MXR changed its logo to a block style. There was a transitional period in which some Phase 90s with script logos had box logo circuits, and vice versa. Production ceased when MXR went bankrupt in 1984.
