MXR Phase 90
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.
When Jim Dunlop bought the MXR brand, production resumed. The Dunlop models have an LED to indicate the effect is engaged, and an optional AC power supply. There are several styles, including the standard block logo version, a reproduction of the script logo version, and an Eddie Van Halen signature model. The 1974 Hand Wired Phase 90 is a recreation of an original 1974 pedal using NOS (New Old Stock) electronic components.
The Phase 90 has an orange enclosure with a single control knob:
- Speed - varies the speed of the phasing effect.
