The original H9 didn't just raise the bar for compact multi-effects pedals — it quietly redefined what a single pedal on a pedalboard could do. Now, the H9 Harmonizer Gen 2 picks up that legacy, dusts it off, and sends it into the future with expanded algorithms, modern ARM processing, and a workflow that actually respects your time.
Built on the same platform as the H90 and H9000, it packs 74 algorithms — spanning delay, reverb, pitch, granular, vocal FX, looping, and more — into a compact, stage-ready enclosure. Just the most capable H9 Eventide has ever shipped, ready to grow with you.
Signature Sound That Actually Delivers
Plenty of pedals promise studio-quality tone. The H9 Gen 2 is one of the rare ones that actually delivers. Built on modern ARM processing and Eventide's proprietary SIFT technology, this thing handles polyphonic pitch shifting with the kind of accuracy that makes other pedals look like they're guessing. It covers the full H90 algorithm lineup alongside all 52 legacy H9 Max algorithms — so whether you're deep into lush reverbs, experimental pitch effects, or something in between, there's plenty of territory to explore.
74 Algorithms, Zero Compromises: The complete H90 and H9 Max libraries live here — delay, reverb, pitch, granular, vocal FX, looping, and more. If you can imagine it, there's probably an algorithm for it, and if there isn't, an update is likely on its way.
SIFT Polyphonic Pitch Technology: Proprietary Spectral Instantaneous Frequency Tracking powers algorithms like Polysynth, Polyphony, Polyflex, and Prism Shift. It's the kind of pitch shifting that stays pristine even when you're throwing a lot at it.
True Spillover Between Presets: Seamless transitions, no clipped tails, no awkward silences. Your effects flow like one continuous sound, not a series of hard stops.
A Workflow Built for the Stage, Not the Manual
If you've ever spent ten minutes in a menu trying to change a single parameter mid-gig, you already know why this matters. H9 Gen 2 was redesigned from the ground up to be faster and more intuitive, with a larger 2.5" display, three dedicated Quick Knobs, and a streamlined three-mode workflow that puts the right controls exactly where you need them. It still has the compact footprint players expect — it's just a lot less likely to make you question your life choices during a soundcheck.
Select, Bank, and Perform Modes: Three focused workflow modes handle preset browsing, live organization, and real-time performance. Each mode does its job without getting in the way of the others.
HotSwitch and HotKnob Macro Control: Instantly toggle between two parameter states or sweep an effect in real time. Less menu-diving, more actually playing.
Full Parameter Control, No App Required: Every parameter is accessible directly from the pedal. The Eventide Control app via Bluetooth and USB-C is available when you want it — not required when you don't.
Built to Fit Any Rig — Now and in the Future
The H9 Gen 2 was engineered to slot cleanly into just about any setup you can throw at it. Dual instrument and line-level I/O handles both pedalboard and studio duty, flexible routing covers Wet/Dry and Pre/Post configurations, and 5-pin MIDI I/O keeps it playing nicely with the rest of your gear. And unlike most gear that hits a ceiling the moment it ships, H9 Gen 2 keeps growing. New algorithms roll out as firmware updates, legacy H9 Classic presets transfer over without a hitch, and 1,000+ presets come loaded out of the box — meaning the pedal on your board today will be a noticeably better pedal a year from now, at no extra cost.
Flexible I/O for Stage and Studio: Dual instrument and line-level inputs and outputs mean this pedal works as comfortably in a recording session as it does at the back of a dark venue during load-in.
5-Pin MIDI, Expression, and Aux Control: Full connectivity for integration into larger rigs, automated setups, or any situation where you need precise, hands-free control.
Continuous Algorithm Updates: New algorithms roll out as firmware updates. It's the pedal equivalent of buying a car that keeps getting faster over time — without the dealership calling you about an extended warranty.
The Best H9 Eventide Has Ever Made
The H9 Harmonizer Gen 2 is a full reimagining of one of the most beloved compact pedals in modern effects. It packs the complete H90 algorithm library, ARM-based processing, true spillover, and a vastly improved workflow into a stage-ready format, with no subscriptions or fine print attached.
For longtime H9 users, it's everything you loved, only better. For players new to Eventide, it's the most direct entry point into the flagship effects platform. Either way, your pedalboard just got a serious upgrade.

Frequently Asked Questions
The H9 Gen 2 expands on the H9 Max with the full H90 algorithm library (74 algorithms total), modern ARM processing, true spillover between presets, and a redesigned interface with a larger display and improved workflow. It's fully backward compatible with all H9 Classic presets, so nothing you've built is lost.
No. The H9 Gen 2 ships with the complete H9 Max and H90 algorithm libraries included — no subscriptions, no hidden unlocks. New algorithms will continue to be added via firmware updates at no additional cost.
Yes. Dual instrument and line-level I/O, flexible routing options (Wet/Dry and Pre/Post), and MIDI integration make it a practical choice for pedalboards, amp loops, hybrid rigs, and studio setups. It adapts to the signal flow rather than forcing you to work around it.
Absolutely. Full parameter control is available directly from the pedal without needing the Eventide Control app. The app is there when you want deeper editing or wireless control via Bluetooth — but it's never required.
Yes, the H9 Gen 2 is fully compatible with all H9 Classic presets. Every sound you've dialed in on an H9 Max, Core, or Standard transfers over without any reworking required.
