Eventide H9 Harmonizer Gen 2 Multi-Effect Guitar Effect Pedal Multi-FX Gen2

The Next Generation of Harmonizer
The H9 Harmonizer Gen 2 brings Eventide’s iconic multi-effects pedal into a new era delivering studio-quality sound and creative flexibility in a compact, performance-ready format.

Building on everything players loved about H9 Classics (H9 Max, H9 Core, H9 Standard), H9 Harmonizer expands the platform with the full H90 algorithm lineup, modern ARM processing, and a faster, more intuitive workflow for today’s stage and studio rigs.

Designed to Grow
The H9 Harmonizer is built as a long-term platform. It includes the complete H9 Max library and remains fully compatible with legacy presets. No subscriptions or hidden unlocks. New algorithms will continue to roll out as updates.

Integrated with Eventide Control and powered by a modern software foundation, The H9 Harmonizer is designed to evolve alongside the needs of today’s players.

Signature Sound
H9 Gen 2 combines the full legacy of the original H9 with the expanded creative range of the H90. It includes the full 74-algorithm lineup found in the H90, including all 52 original H9 Max algorithms, spanning delay, reverb, pitch, granular, vocal FX, looping, and much more. For longtime H9 users, it’s everything you love, now expanded. For new players, it’s the most direct path into Eventide’s flagship effects platform.

Built on the same modern ARM processing as the H90 and H9000, H9 delivers higher- fidelity sound, improved overall performance, and true spillover on preset changes for seamless transitions. Proprietary Spectral Instantaneous Frequency Tracking (SIFT) tech produces pristine polyphonic pitch shifting and powers algorithms such as Polysynth, Polyphony, Polyflex, and Prism Shift.

Built to Play
H9 Harmonizer is designed to make great sounds easier to access. A larger 2.5" display, updated controls, and a simplified interface make navigation faster and more intuitive than the original H9, while preserving the immediacy players expect from a compact pedal format.

Its workflow is built around three core modes: Select Mode, Bank Mode, and Perform Mode. Together, they create a faster, more performance-ready experience for browsing presets, organizing sounds for live use, and controlling effects in real time. With HotSwitch and HotKnob macro control, plus flexible footswitch behavior, H9 feels less like a menu-driven processor and more like an actual instrument.

Made for Modern Rigs
H9 supports one algorithm at a time, featuring flexible I/O and global or preset-specific settings. The various routing options make it easy to slot into pedalboards, amp loops, hybrid rigs, and studio setups.

Get connected quickly and easily with Bluetooth support for H90 Control, 5-pin MIDI I/O, stereo audio I/O, as well as expression and aux control. The next generation of H9 is ready for the demands of stage and studio. It’s compact enough to simplify a board, yet connected enough to anchor a modern rig.
