Electro-Harmonix XO Frequency Analyzer


  • Blend
    mixes the input signal with the effected signal
  • Shift
    controls the difference in frequency with the input signal
  • Fine
    same as shift, but for fine-tuning
  • Filter/On



Adds moving harmonies to the note or chords being played. Unlike other Ring Modulators, the Frequency Analyzer has controllable high order filters that reduce cross distortions and enhance the variations. The course and fine control let the user set a single frequency that will then be both added and subtracted from the original note or chord. Blend control lets you mix the new notes with the original. This is a must esoteric pedal, especially for techno cats. Devo had their biggest hit using the Frequency Analyzer.
