Information
Electro-Harmonix
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.
