MXR® Phase 90® Phaser (M101)
The MXR Phase 90 is a classic single-knob analog phaser that delivers everything from subtle spatial shimmer to fast, swirling modulation with the twist of a single control. Its simple design and instantly recognizable sound have made it a staple on countless recordings for decades.
With just a Speed control, the Phase 90 makes it easy to dial in movement that enhances leads, thickens chords, or adds motion to clean and driven tones alike. The effect remains musical and responsive across its full range, never overpowering the original signal.
Built around a true hardwire bypass circuit and housed in MXR’s rugged enclosure, the Phase 90 works equally well with guitar, bass, keyboards, and other instruments, making it a versatile modulation pedal for both stage and studio use.
