The Eventide H9 Harmonizer is a staple in Eventide's lineup, giving you all of the algorithms from their "big box" pedals (the TimeFactor, Space, PitchFactor, and ModFactor), as well as additional algorithms exclusive to the H9 series. This particular one was only used at home in a studio environment and still has the plastic on the display. It comes with the original box and papers. Excellent condition.
