A firm favourite of Eddie Van Halen the MXR M101 Phase 90 is the ONLY phase pedal for many aspiring rockers.

The MXR Phase 90 adds a shimmery velocity to lead passages or a more dramatic swoosh to muted strumming. Not just for guitars; it works well with bass, keyboards and even vocals. Vary the speed from a subtle, long cycle to a fast, watery warble...and myriad vintage vibrations in between.
