Eventide H90 Harmonizer Multi-Effects Guitar and Bass Processor Pedal

For over 50 years, Eventide has helped shape the sound of countless artists and producers. The Eventide H90 Harmonizer® continues that legacy as a next-generation multi-effects processor, combining legendary sound quality with powerful new technology. Whether you need essential everyday effects or cutting-edge sound design tools, the H90 delivers exceptional versatility with 62 premium algorithms, hundreds of professionally crafted presets, and an intuitive interface designed for guitarists and performing musicians. With extensive connectivity and flexible routing options, it's built to become the centerpiece of any pedalboard or professional guitar rig.

Next-Generation Processing Power

Built on a modern ARM-based processing platform inspired by Eventide's flagship H9000 Harmonizer, the H90 provides significantly more processing power than previous generations. Alongside the acclaimed reverbs, delays, modulation effects, and pitch-shifting algorithms from the H9 Max, it introduces 10 all-new effects, including advanced polyphonic pitch shifting with exceptionally fast tracking and natural, artifact-free performance.

Powered by Eventide's proprietary SIFT (Spectral Instantaneous Frequency Tracking) technology, the H90 delivers remarkably accurate pitch detection while opening the door to entirely new generations of creative effects.

Enhanced Algorithms and Improved Performance

Every effect inherited from the H9 Max benefits from the H90's upgraded DSP engine, offering improved overall performance and responsiveness. New features such as enhanced pitch tracking, quantization, and expanded functionality previously exclusive to Eventide's dot9 pedals and software plug-ins provide even greater flexibility for both studio and live applications.

Dual-Algorithm Sound Engine

One of the H90's standout features is its ability to run two effect algorithms simultaneously within a single Program. Effects can be routed in series or parallel, while true preset spillover ensures seamless transitions between sounds. This powerful architecture allows players to create rich, layered textures and complex effect chains without compromising audio quality.

Hundreds of Ready-to-Play Presets

The H90 includes hundreds of factory Programs covering a wide range of musical styles, instruments, and performance scenarios. In SELECT Mode, presets can be browsed sequentially using the bright OLED display, while BANK Mode provides instant access to groups of three Programs—ideal for quickly switching sounds during live performances. Custom playlists make organizing setlists and favorite presets simple and efficient.

Designed for Live Performance

Every aspect of the H90 has been engineered with live performance in mind. The redesigned control panel features five multifunction push encoders, seven illuminated buttons, and a high-resolution OLED display, providing fast access to essential controls and real-time parameter feedback.

In PERFORM Mode, six programmable footswitches can be assigned to functions such as tap tempo, preset bypass, effect bypass, and expressive performance controls including reverb freeze, pitch bending, and delay repeats. Three dedicated HotSwitches allow multiple parameters to be changed instantly with a single press, making complex live performances effortless.

Flexible Control and Connectivity

The H90 offers extensive control options for virtually any setup. The dedicated PERFORM HotKnob enables quick adjustment of assigned parameters, while three customizable Quick Knobs provide instant access to frequently used controls. Dual inputs support expression pedals or auxiliary switches with up to three external buttons, and comprehensive MIDI implementation allows deep integration with advanced guitar rigs and professional switching systems.

H90 Control Software

Managing the H90 is simple with H90 Control, Eventide's dedicated editor for Mac and Windows. The software allows users to organize Programs and presets, edit settings, perform firmware updates, and import or export user lists through an intuitive interface, making it easy to keep your pedal fully customized and ready for every performance.
