General

With the H90 Harmonizer, Eventide give guitarists the opportunity to kit themselves out with an exceptionally potent multi-effects pedal loaded with an intuitive interface and every input and output needed to guarantee seamless live or studio rig integration. Whether you reach for one of the 62 presets or start experimenting with building new sounds from scratch, it won't take long before you realise why professional musicians have been gearing up with Eventide pedals for years. With hundreds of possible program combinations and ample connection potential, the Eventide H90 is fully prepped to form the beating heart of countless set-ups and comes complete with a universal power supply, a set of rubber feet and a USB cable.

The H90 Harmonizer: Advanced Tech

Underneath the sleek face of the H90 Harmonizer hides a modern circuit that's based on ARM processors and Eventide's flagship, the H9000. This not only places reverbs, delays, modulation and pitch shift effects at your feet, but a stack of fresh effects as Eventide have equipped the H90 with ten powerful algorithms that lift each of these iconic effects to new heights - courtesy of Eventide's own SIFT (Spectral Instantaneous Frequency Tracking) tech as well as ultra-low-latency Polyphonic Pitch Shifting. Be sure to check out the specifications below for the full overview of every new feature.

Easy to Use

In addition to a hi-resolution OLED display, the H90 Harmonizer comes fitted with five controls and seven LED indicators to help you fire up and tweak the various options with ease, while the footswitches make switching between the SELECT, BANK and PERFORM modes as effortless as can be. In PERFORM mode, you're getting six programmable footswitches that can be assigned to tap tempo, different presets, reverb freeze or other parameters, and Dual Mode opens up the option to use the four-cable method or hook up two stereo instruments at the same time. To sum it all up, the options are literally endless.
