The first time I plugged in an Eventide, I immediately understood why this brand had such a reputation. The H9, then the H90 — it was the ultimate Swiss Army knife of effects: delay, reverb, harmonizer, pitch, modulation, all in a single unit. And now Eventide is back with a new generation that grabbed my attention straight away. Let me introduce you to the H9 Harmonizer Gen 2 — honestly, it’s exactly the kind of pedal I’d been waiting for. In this article, we’ll look at what’s changed, what’s on board, and who it’s really built for.
The best way to understand the H9 Gen 2 is to think of it as a streamlined H90. The H90 runs two algorithms simultaneously; the Gen 2 runs just one at a time. And for the vast majority of musicians, that's already more than enough. Not everyone needs to stack two reverbs, a harmonizer, and three granular delays in parallel.
What you keep is the sonic quality of the H90, in a more compact and more affordable format. With the Gen 2, Eventide completely simplifies the experience: everything is included from day one. No a la carte download system, no marketplace. Plug in and you have access to the entire ecosystem.
And when I say everything, I really mean everything: the algorithms from the H9 Max and the H90 -- that's 74 algorithms and around 1,000 presets. Delays, reverbs, modulation, pitch shifter, octaver, multi-effects. A fully-stocked effects platform for any instrumentalist -- and vocalists too.

A streamlined H90: what’s actually different?
The best way to understand the H9 Gen 2 is to think of it as a trimmed-down H90. The H90 lets you run two algorithms simultaneously. The Gen 2 runs just one at a time. And honestly, for the vast majority of musicians, that’s already more than enough.
Not everyone needs to stack two reverbs, a harmonizer, and three granular delays in parallel. What everyone does appreciate, though, is getting the sonic quality of the H90 in a more compact, more affordable package. That’s exactly what this new version sets out to deliver.
The Gen 2 is a clear answer to everyone who loved the H9 Max. Back in the original H9 days, you had to collect algorithms one by one — or go for the Max version to get everything at once. With the Gen 2, none of that hassle: it’s all there from the moment you unbox it.
74 algorithms, 1,000 presets: everything included from day one
This is where the Gen 2 really delivers. Eventide has completely rethought the experience: everything is included from day one. No a la carte download system, no marketplace. Plug in and you have access to the entire ecosystem.
And when I say everything, I really mean everything. The Gen 2 carries the algorithms from the H9 Max and the H90: we’re talking 74 algorithms — around 1,000 presets in total. Delays, reverbs, modulation, pitch shifter, octaver, multi-effects… It covers virtually everything Eventide has perfected over the years.
Here are the main effect families you’ll find on board:
- Delays and reverbs: from tight slapback to vast ambient swells
- Harmonizer and Harmonizer+: the quintessential Eventide signature
- Pitch shifter and octaver: transpositions and layered voices
- Modulation, granular, synth, and looper: for sound design
- Distortion, EQ, and utilities: rounding out the toolkit
Not just for guitarists
This is something people often overlook with Eventide. Sure, guitarists will love it, and so will bass players. But keyboard players will find an absolutely formidable machine here too — because it features proper instrument and line-level inputs and outputs.
A synth, a keyboard, a drum machine: all of it works perfectly. And it can even pull its weight for vocalists. Thanks to the Harmonizer+ suite, the Gen 2 can become a full-on vocal processor. There’s even the MixingLink preamp — sold separately — that rounds out the system.
And when you know Eventide’s history with vocal harmonizers, you know they’re operating in territory they’ve mastered for decades. This is simply a top-tier effects platform for any instrumentalist or vocalist.
Pitch technology inherited from the H90
You get the same tech as the H90 here — the engine powering polyphonic algorithms like Polyphony, Polyflex, and PrismShift. If you’ve ever had a chance to try a H90, you’ll know that the polyphonic processing is simply stunning.
Pitch shifts are far more natural-sounding. Harmonies are cleaner. And all the synthesis effects clearly operate at a premium level. It’s the celebrated SIFT technology doing the heavy lifting behind these pitch algorithms.
Polyphonic pitch is where the Gen 2 truly sets itself apart. You can transform a single line into a full arrangement, or widen a mono take with subtle micro-shifts. Even when you push into bold intervals, it stays musical.
An interface finally built for the stage
The other major update is the interface. The original H9 was great, no doubt — but let’s be honest, you often ended up reaching for the app. With the Gen 2, Eventide has completely rethought the experience, and it makes a real difference day to day.
The workflow is straightforward. You have a main encoder to scroll through your sounds, plus 3 smaller knobs for direct access to each effect’s key parameters. A switch lets you bypass or engage the effect, and you can navigate between banks both up and down with ease.
You also have several modes accessible from the button pad:
- Select: browse your sounds in detail view or performance view
- Bank: scroll up and down through your banks
- Perform: switch between detail mode and performance mode on the fly
- Preset / parameters: choose and build the effects you want
When you dive into the presets, you can choose your destination library. Factory for ready-made presets, User 1 and User 2 for building your own set lists. You can browse by effect category (delay, granular, harmonizer+, modulation, reverb, synth…) or go straight to any of the 74 algorithms. There’s no shortage of things to explore.
You can organise your H9 exactly how you want for live use: every effect dialled in and sorted into set lists in your preferred order. The result: far less time navigating menus, and far more time actually playing.
Connectivity: everything you’d expect from a modern pedal
On the connectivity front, nothing is missing. Eventide has ticked every box for integrating the pedal into a modern rig:
- Bluetooth: tweak your sounds cable-free (Mac and iPad, no app required)
- MIDI: for automation and preset changes
- Expression pedal input: control mix, pitch, feedback, or any key parameter
- USB-C: for firmware updates and editing
You can also access the system’s global settings by holding both button pad keys: general settings, input/output parameters, and MIDI configuration. Everything you need to tailor the unit precisely to your setup.
And how does it actually sound?
The H9 Gen 2 is defined by a studio-grade quality that holds up clearly in a live context. The sound is precise and detailed, with that characteristic sense of depth that’s unmistakably Eventide. The pitch algorithms stay musical even when you push into bold intervals or layer multiple voices.
In modulation and delay, it moves effortlessly from the subtle (stereo widening, light chorus, clean slapback) to the extreme (granular, stutter, swells, and glitch). The reverbs can sit quietly behind a part, adding body and depth, or swell into enormous ambient landscapes. Above all, it responds to your playing: consistent dynamics, respected attack, and a responsiveness that makes you want to play with the effect rather than simply switch it on.
If you’ve had your eye on the H90 but it was out of budget — or if you simply don’t need to run two algorithms at once — the Gen 2 is the one for you. It’s the best of the H9 and the best of the H90, in a compact, more accessible package.
FAQ — Eventide H9 Harmonizer Gen 2
What’s the difference between the H9 Gen 2 and the H90?
The H90 runs two algorithms simultaneously. The H9 Gen 2 runs just one at a time. For the vast majority of musicians, that’s more than sufficient — and you still get the sonic quality of the H90 in a more compact, more affordable format.
Do you need to purchase algorithms separately?
No — and that’s the whole point. With the Gen 2, everything is included from day one: all 74 algorithms and around 1,000 presets. No a la carte downloads, no marketplace — unlike the original H9.
Is the H9 Gen 2 only for guitarists?
Not at all. Thanks to its instrument and line-level inputs and outputs, it works perfectly with a synth, keyboard, or drum machine. And with the Harmonizer+ suite and the MixingLink preamp (sold separately), it can even serve as a full vocal processor.
What power supply does the H9 Gen 2 need?
It requires a 9 V DC supply with 800 mA recommended. The power supply is not included — make sure to add a compatible one to your order if you don’t already have one.
Can you edit the H9 Gen 2 wirelessly?
Yes. It features Bluetooth on Mac and iPad — no app required — so you can adjust your sounds cable-free. You also have MIDI, an expression pedal input, and a USB-C connection for updates and editing.
My verdict on the H9 Gen 2
In the end, I think this H9 Gen 2 will resonate with a lot of people. Those who’ve been waiting for a true successor to the H9, and everyone who’s looked at the H90 but either didn’t have the budget or simply didn’t need to run two algorithms at the same time.
I may be repeating myself, but this really is the best of the H9 and the best of the H90 — in a compact, more accessible package. If you’re after an effects platform that’ll serve you for years to come, on stage and in the studio, this one has a very strong case. Now it’s just a matter of what sounds you’ll pull out of it.
