MXR M101 Phase 90 Pedal

Plug in and freak out. The M-101 Phase 90 adds a shimmery velocity to leads or a dramatic swoosh to muted playing, and works well for many instruments.
The MXR M-101 provides classic 4 stage phasing sound with continuous variable speed control. Phase 90 fixed regeneration level adds intensity and is particularly effective for keyboards. This device has found its way into many of Eddie Van Halen's recordings, adding a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. The M-101 phaser is not just designed for guitars; it works well with basses, keyboards, and even vocals and appears in all of these guises on Dweezil Zappa's Z album, 'Music For Pets,' which reveals its flexible and hip nature.


- Foot accessible speed control knob
- LED on/off indicator
- Powered by the Dunlop ECB03 (earlier versions use ECB02) AC Adapter and/or 9 volt battery

"Classic Effect Pedal!!"

I love this pedal. I can easily see why so many guitarist chose to use this secret weapon. It helps make my guitar playing sound epic and timeless. Nice and sturdy little device with the classic orange color. I'm mad that I didn't decide to get the Phase 90 sooner! Buy this pedal and you won't regret it!!
