Eventide H9 Harmonizer Review (2021)

After two and a half years in development the multi-award winning Eventide H9 Harmonizer delivers the renowned sound Eventide is known for. Highly acclaimed for their stompbox series incl. PitchFactor, ModFactor, TimeFactor and Space. This multi effects guitar pedal allows for the use of all Eventide’s stompbox effects in just one unit, containing over 40 effect algorithms for you to choose from. The simple and sleek front-end design contains a LED display, five control buttons (hotknob, preset, x/y/z), a rotary dial, and a left and right foot switch.

Eventide has been a huge player in the music industry, and continues to deliver time and time again. The United States company has been developing and manufacturing digital audio processors, DSP software and guitar effects since the early 70’s.

With that said, it is not entirely essential, as every function can also be controlled using the front panel of the H9. The H9 Control app is available for free at Eventides official website to put onto your iOS device.
