New Technology, New Effects


The H90 Harmonizer features modern ARM-based architecture derived from the world’s most powerful effects processor, Eventide’s flagship H9000 Harmonizer. This paves the way for the ongoing creation of more advanced effects processing techniques. As a result, the pedal not only offers the iconic reverbs, delays, modulation, and pitch-shifting effects of the H9 Max but goes far beyond with ten new powerful algorithms including state-of-the-art, fast-tracking, and warble-free Polyphonic Pitch Shifting. Eventide’s proprietary SIFT (Spectral Instantaneous Frequency Tracking) technology clears the road ahead for next-gen effects both long-imagined and unimaginable.


Eventide H90 Harmonizer Multi-effects Pedal Features:

  • Contains 62 effect algorithms total, from the most basic always-on sounds to cutting-edge experimental modulation
  • Utilizes the same ARM-based architecture from the Eventide flagship H9000 Harmonizer for studio-quality fidelity
