Eventide had left its H9 untouched for a long time. The brand is correcting that with the H9 Harmonizer Gen 2, a revamp that squeezes the core of its flagship H90 engine into the compact enclosure that made the original so successful. Available since 24 June 2026, it is priced at $599 (€699). Behind the “pedal” packaging, this is a serious effects processor getting a long-overdue update.
A pedal that hadn’t really changed since 2013
The original H9 came out in 2013 and has never really been replaced: thirteen years on the market, an unusually long life for a digital product. Its concept — one algorithm at a time, but drawn from the best of the Eventide catalogue, with algorithms purchased à la carte — made it a discreet standard on pedalboards and in effects racks alike. The problem was that the electronics were showing their age. Gen 2 doesn’t change the formula: it brings it up to date.

The H90’s 74 algorithms in a pedal enclosure
This is the real news. The H9 Gen 2 includes the full library from the H90 and H9 Max, i.e. 74 algorithms and more than 1,000 factory presets. You get the company’s signature delays and reverbs, the polyphonic SIFT pitch-shifting that built the brand’s reputation, granular engines, vocal effects, synth-style tools and looping. Crucially, the pedal remains compatible with original H9 patches: long-time users can recover their sounds without rebuilding everything from scratch.
Under the bonnet, Eventide has moved to a modern ARM platform, with redesigned converters and improved overall fidelity. In practical terms, what changes day to day is:
- 2.5-inch OLED display, three Quick Knobs and a button matrix for direct parameter access;
- Full control from the pedal itself, with no mandatory app — the Eventide Control app is still there for updates, preset management and MIDI mapping;
- Stereo inputs/outputs, compatible with both instrument and line level;
- Flexible Pre/Post and Wet/Dry routing, with spillover between presets;
- HotKnob and HotSwitch macros, built-in tuner, programmable footswitches;
- USB-C connectivity, 5-pin DIN MIDI, expression pedal and auxiliary switch input.

H9 Gen 2 or H90: where is the line?
Eventide quite deliberately positions the Gen 2 below its H90. The difference comes down to one word: simultaneity. The H90 has a dual-core engine capable of running two algorithms in series or in parallel; the H9 Gen 2 is limited to a single algorithm at a time. The rest of the library, however, is identical.
| H9 Harmonizer Gen 2 | H90 Harmonizer | |
|---|---|---|
| Simultaneous algorithms | 1 | 2 (series or parallel) |
| Library | 74 algorithms | 74 algorithms |
| Factory presets | 1,000+ | 1,000+ |
| I/O | Stereo, instrument and line | Stereo, instrument and line |
| Format | Compact pedal | Wider enclosure |
| Price | $599 / €699 | around $899 |
For anyone who doesn’t need to stack two effects, the Gen 2 therefore offers the same sonic pool for roughly three hundred dollars less. It’s a smart positioning: bringing back users of the old H9 without cannibalising the flagship model.
Line level: the small detail that takes the pedal off the pedalboard
I’m deliberately skipping the stompbox wars, because that’s not where this H9 interests me. The point that matters, to my mind, is this stereo input/output that accepts line level. Back when I was running a studio, the Eventide Harmonizer — its ancestor, the H3000 — lived in the rack, patched to an aux send on the console to double a vocal or widen a lead. A pedal that properly handles line level is exactly that: an effect you patch onto an aux send without a reamp box, no longer just something sitting on the floor. For a hybrid home studio, that’s what marks the difference between a guitarist’s gadget and a real production tool. Eventide doesn’t shout about it on the box, but technically, that’s the reason it deserves attention here.

An update that secures the future
Switching to an ARM architecture is not just about fidelity: it also provides a sustainable software base, easier to maintain via firmware than the ageing 2013 platform. Eventide is giving itself the means to keep expanding the Gen 2 over time, as the company knows how to do — remember that it doesn’t hesitate to resurrect its own legacy, as with the relaunch of its Music Mouse software instrument. In the field of touch-based, mobile effects processors, the H9 Gen 2 squares up to products as different as the Korg Kaoss Pad V on the performance side or the Alphatheta RMX-IGNITE in the DJ world, each championing a vision of effects as an instrument in its own right.
At $599, the H9 Harmonizer Gen 2 doesn’t reinvent anything: it takes a tried-and-tested formula, gives it the electronics it deserved and the most comprehensive algorithm catalogue ever assembled in an Eventide pedal. For a hybrid studio or for live use, it’s one of the most straightforward ways to have that Eventide sound at your fingertips. All specifications are detailed on the Eventide product page.
