State-of-the art effects processing—in a pedal.

The 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. Discover why top artists and producers have chosen Eventide through the years with 64 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

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 10 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.

That's not all. All previous H9 Max algorithms have been enriched with features previously only available on the dot9 pedals and plug-ins. Others have been enhanced to take advantage of the new advanced pitch shifting.

Twin-Turbo Program Power

Two of these already impressive algorithms can be combined into a Program to create novel, inspiring sounds. 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 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.

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. Two large push knobs allow you to switch between SELECT, BANK and PERFORM modes with ease. In PERFORM mode, you get six programmable footswitches. Map functions like tap tempo, preset, insert bypass or momentary states; use them to engage options like reverb freeze, pitch flex or delay repeat; 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 wasn't enough, take advantage of the pedal's extensive MIDI control.

The H90 comes with hundreds of factory Programs which 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 a 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.
