Eventide H9 Core Harmonizer

The Eventide H9 is a compact, fully programmable multi-effects pedal. In addition to its prodigious sonic qualities, the pedal’s controls have been yolked down to a single knob and two footswitches, allowing for quick and effective on-the-fly parameter changes. 

In addition to the front panel, the H9 can be controlled via the free H9 Control editor/librarian. This application can be downloaded to a computer or iOS device and allows intuitive control over live editing, preset creation and management, and altering system parameters. It can even connect to iOS devices via BlueTooth for an added layer of convenience.
