Electro-Harmonix 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



One of the most sophisticated and unusual effects in the Electro-Harmonix line, the Frequency Analyzer, used by Devo and others, adds moving harmonies to the original note while controllable high order filters reduce cross product distortion. From tunable three-voice harmony to anarchic microtonal sounds, the Frequency Analyzer is an esoteric accessory for all instruments.
