The Eventide H90 Harmonizer is Eventide’s next-generation multi-effects pedal. Whether you want high-quality bread-and-butter effects or experimental sounds unheard, the H90 has everything you need to inspire your creativity with an intuitive UI designed with players in mind, 62 effect algorithms, and hundreds of Program combinations curated for a variety of instruments and genres. With its comprehensive I/O and flexible routing options, the H90 is designed to be the heart of your rig.

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.

Harmonizer+ is Eventide’s groundbreaking suite of vocal effects, derived from the flagship H9000 and engineered with cutting-edge technology for shaping and transforming vocals, live or in the studio.

Harmonizer+ Expands the H90’s Capabilities with Two New Studio-Grade Algorithms:

VocalTune: Sculpt your voice with ease. VocalTune delivers powerful vocal enhancements with pitch correction, precise scale quantization, pitch and formant shaping, plus gate and compression controls for a polished, expressive sound.

VocalShift: Shape your harmonies with precision. VocalShift creates everything from subtle doublings to lush choruses using three independent voices, each with pitch and formant control, intelligent scale recognition, and performance features like voice soloing, pitch glide, and pitch hold.
