Built with a dual stomp design in a durable metal chassis, individual voice control knobs for contouring the harmony of each section, and a large, easily readable harmony key display sitting front and center in the interface, the DigiTech Harmony Man is your right-hand pedal for nailing down vocal performance. Built on a pitch detection engine conceived using musIQ technology which automatically detects aberrant notes and chords and corrects them, this pedal's three-part harmonies and consistent performance make it a prime (and affordable) choice.
