Electro-Harmonix Frequency Analyzer Ring Modulator Pedal

The Frequency Analyzer Ring Modulator Pedal from Electro-Harmonix gives you two additional notes in addition to the one you play if you are playing chords. This pedal features a 40V/100 mA tip positive, external power supply adapter. By turning your Blend dial, you can filter out your original note, and the volume of the original note goes down or up, but the overall volume remains constant. The Shift knob gives you basic frequency, and has a range of four to five octaves. The Fine knob permits fine tuning of the Shift control and covers almost any octave with just a little twist.
