MXR M-101 Phase 90



  • Speed
    controls the speed/rate of the LFO wave that controls the effect


Different versions:

  • Script Logo: 1974-1977
  • Block Logo: 1978-...


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. 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.
