The MXR Phase 90 was one of the first phaser pedals on the market in the 1970s. It was very successful and much sought after by many instrumentalists then, as well as today. It enhances the tone of almost any instrument, including guitar, keyboards, and bass.
Just one twist of the Rate knob takes you from smooth and subtle modulation to a high-velocity swirl. The unique lush tone of Phase 90 is legendary and has been heard on everything from guitar, keyboards, and vocals to who knows what! For well over 40 years, the MXR Phase 90 phase shifter has been the backbone of effects pedalboards for countless musicians.
The MXR Phase 90 is an iconic guitar effects pedal, and endless licks and chords have been improved by its tonal qualities. Call Andy's and get yours today.
