The H9 Harmonizer Gen 2 multi-effects pedal brings Eventide’s beloved H9 series into a new era, pairing studio-quality sound with creative flexibility in a performance-ready package. Building on everything players loved about the original H9 lineup, Gen 2 expands the platform with a full collection of the H90 algorithms, modern ARM processing, and a faster, more intuitive workflow designed for modern rigs. At its core are 74 algorithms and over 1,000 presets, with ongoing updates to keep the lineup growing long after it reaches your board. True to its name, the Harmonizer Gen 2 also introduces high-fidelity polyphonic pitch-shifting through Eventide’s SIFT technology, powering lush harmony and pitch effects that respond naturally to full chords rather than single notes. A redesigned interface with a larger display, Quick Knobs, button pads, and HotSwitch macros rounds up the updates to this next-gen unit, ensuring every important parameter is within reach, whether you’re dialing in a patch at home or switching sounds mid-set. Combining a definitive array of Eventide’s most defining algorithms and an expansive, expressive platform, the H9 Harmonizer Gen 2 is here to evolve your sound.

A deep, ever-expanding sound library
Combining the full H90 and H9 Max collections into 74 algorithms with more than 1,000 presets to pull from, the H9 Harmonizer Gen 2 is expansive. This collection provides access to Eventide’s most celebrated reverbs, delays, modulations, and pitch effects, from shimmering ambient washes to tight rhythmic delays and much more, all in a single pedal. Rightfully named, the Harmonizer comes to life via Eventide’s SIFT polyphonic pitch-shifting, which powers Polysynth, Polyphony, Polyflex, and Prism Shift for harmonies and pitch effects that track full chords with remarkable clarity. And because new algorithms arrive through ongoing updates, your effects library will continue to grow, ensuring your pedal stays current with Eventide’s latest sonic developments.

A faster, more intuitive workflow
Gen 2’s redesigned interface makes navigating its deep library quicker and more intuitive than ever. An improved 2.5-inch display anchors an updated UI built around Quick Knobs, button pads, and HotSwitch macros, giving you hands-on control over your sounds without complex menus. Dedicated Select, Bank, and Perform modes let you easily organize and recall patches, while wireless Bluetooth control on Mac and iPad enables deep editing and preset management on a larger screen. For players who want to expand the platform's capabilities into vocal processing, the H9 Harmonizer Gen 2’s optional Harmonizer+ suite transforms vocals when paired with the MixingLink preamp (sold separately).

Expand your studio or stage rig
Eventide designed the H9 Harmonizer Gen 2 to slot seamlessly into modern stage and studio setups. Instrument and line-level I/O create flexible routing options, letting the pedal sit comfortably in front of an amp, in an effects loop, or within a studio signal chain. Likewise, a full connectivity set gives you room to integrate controllers and expand your control options with USB-C, MIDI, an aux switch input, and an expression pedal input, while true effects spillover lets reverb and delay tails ring out naturally as you switch between presets. A built-in tuner rounds out the package, keeping your performances locked in tune without adding another box to your board.
