Electro-Harmonix Frequency Analyzer

The Electro-Harmonix Frequency Analyzer is one of the most sophisticated effects pedals in the E-H line. It's a ring modulator that adds moving harmonies to the original note while controllable high-order filters reduce cross-product distortion. From tunable 3-voice harmony to anarchic microtonal sounds, the Electro-Harmonix Frequency Analyzer makes an esoteric accessory for all instruments.
