H90 Harmonizer®

Multi-effects Inspiration Engine

Beyond the Effect Horizon

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 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.

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.

Twin-Turbo Program Power

Two of these already impressive algorithms can be combined into a Program to create novel, inspiring sounds. The H90 Harmonizer’s dual algorithm design features true spillover between Programs, series or parallel effect routing, and flexible I/O.

• Two mono inserts allow you to incorporate outboard effects in any configuration or combine them for one stereo insert. Optimize your signal flow with instrument or line level operation and full gain controls to incorporate the H90 into your rig or make it the centerpiece.
• Dual Mode lets you do things like connect using the four-cable method or process two independent stereo instruments at once! Let the H90 Harmonizer take you beyond the effects horizon.

Factory Programs

The H90 Harmonizer comes with hundreds of factory Programs that can be loaded using either SELECT or BANK mode. In SELECT mode, you can navigate your Playlist sequentially without ever missing a detail thanks to the OLED display. In BANK mode, you can quickly load from a bank of three Programs, perfect for cueing up the range of sounds for a song. Organizing your favorite sounds has never been easier, simply load a new Playlist and you’re ready for the next gig! 

Live Performance Machine

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.

Comprehensive UI

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.
