H90 Harmonizer

Multi-effects Inspiration Engine

Discover why top artists and producers have chosen Eventide for over 50 years with the H90 Harmonizer®, 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 spark creativity. Designed with players in mind, it features an intuitive interface, 66 effect algorithms, and hundreds of curated Program combinations for a wide range of instruments and genres. With its comprehensive I/O and flexible routing options, the H90 is designed to be the heart of your rig.

New Effects, Endless Sounds

The H90 Harmonizer features modern ARM-based architecture derived from the world’s most powerful effects processor, Eventide’s flagship H9000 Harmonizer.

Exclusive Algorithms

The H90 not only offers the iconic reverbs, delays, modulation, and pitch-shifting effects of the H9 Max but goes far beyond with new powerful algorithms including state-of-the-art, fast-tracking, and warble-free Polyphonic Pitch Shifting.

Essential Programs

The H90 Harmonizer comes with hundreds of factory Programs that can be loaded using either SELECT or BANK mode. Organizing your favorite sounds has never been easier, simply load a new Playlist and you’re ready for the next gig! 

The H90 Harmonizer is a live performance powerhouse! The front panel has been reimagined with five push knobs, seven LED buttons, and a hi-res OLED display for greater hands-on control and parameter feedback. 

In PERFORM mode, you get six programmable footswitches. Map functions like tap tempo, preset and insert bypass with momentary states, and performance parameters like reverb freeze, pitch flex, or delay repeat. Furthermore, you can make multiple instantaneous parameter changes with three HotSwitches

The comprehensive UI allows you to control any parameter with ease. Adjust expression mappings by hand with the PERFORM HotKnob and engage up to six individual assignable parameters with the three push-button Quick Knobs. Get even more control with two inputs for expression pedals or auxiliary switches with up to three buttons. If that’s not enough, take advantage of the pedal’s extensive MIDI control. 

The H90 Harmonizer’s dual algorithm design features true spillover between Programs, series or parallel effect routing, and flexible I/O.
