Iconic Phase For Any Occasion

Suitable for Guitar, Bass, Keyboards and even vocals, the MXR Phase 90 Guitar Effects Pedal delivers a shimmery velocity to lead licks, and a thick swoosh to any chord. First released in 1972, this all-analog phase pedal has been used on countless classic hits across the years, and is renowned for appearing on many of Eddie Van Halen’s recordings. Its simple one-knob layout allows users to vary the speed from a subtle, long cycle to a much faster warble. Housed in a durable vibrant orange chassis, the Phase 90 is the perfect addition to any pedalboard.
