Description
Overview
The Electro-Harmonix Intelligent Harmony Machine is a powerful harmonizer and pitch shifter designed to instantly create matching harmonies that follow your playing in real-time. By simulating the sound of one or two additional guitarists jamming in perfect sync, this pedal allows a single player to achieve the massive, multi-lead guitar sound characteristic of legendary rock bands and complex multi-part harmonized solos.
Combining impeccable tracking with a genuine musical tone, the Intelligent Harmony Machine transforms simple melodies into sophisticated arrangements. By selecting your musical key, the pedal generates diatonic harmonies that ensure every note remains musically correct and in tune with your song.
Key Details

- Studio Layering: Create complex vocal-style harmonies for guitar tracks without the need for multiple overdubs.
Installation

- Single/Dual Intervals: 6th Down, Perfect 4th Down, 3rd Down, 3rd Up, Perfect 4th Up, Perfect 5th Up, 6th Up, 7th Up.
- Complex Multi-Harmonies: 3rd Up + 5th Up, 3rd Up + 7th Up, Perfect 5th Up + Octave Up.
