Now discontinued, the Frequency Analyser is one of Electro-Harmonix' oldest pedals, famously used by Mark Mothersbaugh of Devo!
The Frequency Analyser is a ring modulator that adds moving harmonies to the note or chords being played, but 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 have pedal, especially for techno cats.
In good condition with original box and power supply.
Please note this pedal operates with a 40v centre positive power supply only.
