Premier Multi-FX pedal with 62 studio-quality effects and flexible I/O
The H90 Harmonizer® is Eventide's next-generation multi-effects pedal. Whether you want high-quality bread and butter effects or experimental sounds unheard, the H90 has everything you need to inspire your creativity with an intuitive UI designed with players in mind. Discover why top artists and producers have chosen Eventide through the years with 66 effect algorithms and hundreds of Program combinations curated for a variety of instruments and genres. With its comprehensive I/O and flexible routing options, the H90 is designed to be the heart of your rig.

Eleven new algorithms exploit the H90's raw power
- Polyphony: Pitch shift chords with ease using SIFT technology. Create rising or sinking chorus and crystals-type effects. Use Freeze to generate pad textures.
- Prism Shift: Generate three voices from a single chord whose intervals are separated, staggered, and pitch-shifted to create four arpeggio types spanning up to three octaves.
- Even-Vibe: Authentic Uni-Vibe emulation reimagined in stereo with envelope followers.
- Head Space: Vintage four-head Tape Delay with classic and modern creative tone shaping controls for grit, spatiality, and character.
- Bouquet Delay: Bucket Brigade Delay (BBD) with modulation, LoFi, and Modern flavours; includes Pitch jump and Self-oscillation performance functions.
- Wormhole: A mega-sized hyper-modulated reverb with pitch warping performance.
- Weedwacker: Two-stage, serial overdrive reminiscent of a famous green pedal.
-Polysynth: a fully polyphonic Guitar to Synth transformer with up to 3 voices, multiple modulation options, and envelope control of the filter cutoff.
-PolyFlex: Bend a chord into a new harmony, perform polyphonic dive bombs, or achieve pedal steel like tones. Fully equipped with detune, freeze, and individual controls for flexing either voice.
-Aggravate: an Octave fuzz inspired by famous classic analog octave fuzzes from the 70's. 
- Sticky Tape: A classic tape echo effect with drive, compression, and wow & flutter controls. Achieve doubling, slapback echo, and studio style tape flange.

Live Performance Machine
The H90 Harmonizer is a live performance powerhouse! The front panel has been reimagined with five push knobs, seven LED buttons, and a hi-res OLED display for greater hands-on control and parameter feedback. Two large push knobs allow you to switch between SELECT, BANK, and PERFORM modes with ease. In PERFORM mode, you get six programmable footswitches. Map functions like tap tempo, preset, insert bypass or momentary states; use them to engage options like reverb freeze, pitch flex, or delay repeat; make multiple instantaneous parameter changes with three HotSwitches.

The H90 comes with hundreds of factory Programs which can be loaded using either SELECT or BANK mode. In SELECT mode, you can navigate your Playlist sequentially without ever missing a detail thanks to the OLED display. In BANK mode, you can quickly load from a bank of 3 Programs, perfect for cueing up a range of sounds for a song. Organizing your favorite sounds has never been easier, simply load a new Playlist and you're ready for the next gig!
