Eventide H90 Harmonizer

Setting the new bar that any powerful multi-effects processors should look up to, Eventide's H90 Harmonizer pedal flawlessly covers effects ranging from delays, pitch-shifting, and more, all with the ability to run two algorithms at the same time. Building on the platform established by the H9, H90 is the most powerful pedal Eventide has ever produced. You could think of H90 as two H9s in one pedal, but it also packs in numerous new effect algorithms, routing options, and performance features that transcend the capabilities of traditional guitar pedals. And with a completely overhauled screen-based interface, H90 is a pedal that you'll always want to be tweaking.

H90 offers a total of 66 different effects algorithms: 52 returning from the H9, and 14 all-new effects taking advantage of H90's impressive processing power. Among these, the Polyphonic algorithm sticks out—it makes use of Eventide's proprietary Spectral Instantaneous Frequency Tracking technology, or SIFT for short. The result is stunning, as even the most dissonant chords and timbres are shifted with perfection. Regardless of your chosen effects, you can use two of H90's algorithms simultaneously, which means you can stack delay into reverb, tremolo into chorus, or any other combination that your heart desires.

With two effects algorithms available at once, H90 also provides incredible flexibility in arranging signal flow. Series and Parallel routings are easily achieved, but even more possibilities are available with external effects. Unlike most pedals, H90 has four inputs and four outputs, with the secondary pairs available for use as two mono inserts or a single stereo loop. Insert loops may be placed anywhere on the effects path, whether it's before, after, or in between H90's algorithm blocks. Alternatively, head into the Global Settings and enable dual mode, which decouples the algorithms into their own independent signal paths, allowing you to set up four-cable method connections with your amp, process two stereo instruments independently, or any other niche audio scenario.

H90's effects and audio routing is only part of the story though, for this pedal sports incredible control capabilities. In Perform mode, you can assign effects parameters to macro-style HotKnobs, instantly recall settings with scene-like HotSwitches, or keep a handful of essential controls at your disposal by assigning them to the QuickKnobs beneath the screen. But if that's not enough for you, H90 also offers two controller ports for expression pedals and auxiliary footswitches, as well as MIDI control over USB-C or traditional 5-pin DIN. Nearly every aspect of an effect may be assigned to an external controller, along with numerous global H90 parameters.

Along with all that you can do on H90 itself, Eventide also offers a companion H90 Control app to configure the pedal from a computer. But the app also provides a graphic interface for quickly adjusting any parameter in real-time, as well as helpful preset and program backups. Considering how powerful it is, calling H90 a pedal almost seems like a disservice. But like the H9 and the other Harmonizer rack units that came before, H90 is a rare instance of a jack-of-all-trades and master of all when it comes to effects processing.
