Electro-Harmonix Intelligent Harmony Machine - Harmony Pedal

The sound of legendary harmonies, without the second guitarist

At Garage à Musique , we all know the thrill of hearing the harmonized two-guitar solos of Thin Lizzy, The Allman Brothers, or Iron Maiden. But how do you recreate that epic wall of sound when you're the only guitarist on stage? The Electro-Harmonix Intelligent Harmony Machine (IHM) is the definitive answer to this problem.

Unlike a basic pitch shifter that adds a fixed interval (often dissonant if you change chords), the IHM is, as its name suggests, intelligent . You select the key of your song, choose your interval, and the pedal instantly calculates the correct note to stay perfectly in scale. It's like having a professional studio musician who can read your mind and play in perfect sync with you.

Two legendary pedals in one box

• Harmoniseur Diatonique Impeccable : Jouez vos gammes et vos solos, l'IHM générera une harmonie intelligente qui respecte la tonalité musicale.

• Mode Pitch Shifter Polyphonique : Envie de gros accords pitchés ou d'effets extrêmes ? Basculez la pédale en mode Polyphonic Override et elle se transforme en une EHX Pitch Fork classique, appliquant des intervalles stricts même sur des accords complets.

• Commutateur Momentané (Momentary) : Le footswitch a deux personnalités. Utilisez-le normalement (On/Off), ou maintenez-le enfoncé pour injecter une harmonie fulgurante ou un changement d'octave juste le temps d'une note, puis relâchez pour revenir à votre son clair.

• Suivi Foudroyant : Que vous jouiez en sweep picking ultra-rapide ou des bends expressifs, le processeur surpuissant de la pédale suit chaque nuance sans aucune latence.

Frequently Asked Questions (FAQ)

1. What is the difference between a Diatonic Harmonizer and a Pitch Shifter?

This is crucial! A standard pitch shifter adds a note at a fixed distance. If you're playing a scale, some notes will sound off. A diatonic harmonizer like the IHM intelligently adjusts to your selected key. It will automatically alternate between major and minor thirds so your solo always remains perfectly in tune and musical.

2. Can the GUI be used to play complete chords?

Yes, but with a subtle difference. The intelligent diatonic harmony is designed for individual notes (solos, melodies). However, the pedal has a Polyphonic Override button. When activated, the pedal stops thinking about the scale and transforms into a powerful polyphonic Pitch Shifter (similar to the famous EHX Pitch Fork), allowing you to play full chords with overlapping octaves or fifths without any dropouts.

3. Is the tracking fast enough for metal or shred music?

Absolutely. Electro-Harmonix used one of the fastest DSP processors on the market. Tracking is instantaneous, meaning even your hammer-ons , pull-offs , and rapid sweep picking passages will be harmonized in real time with surgical clarity.

4. How does the "Momentary" function work?

This is one of its most creative features! Instead of clicking to turn it on and clicking again to turn it off, you can configure the pedal so the effect only activates when you keep your foot pressed down on the button. This is perfect for harmonizing a single word in a solo, or for creating a radical glissando (pitch bend) effect at the end of a musical phrase.

5. Does it work with a bass guitar or a keyboard?

Absolutely. While it's a dream for lead guitarists, the circuit handles lower frequencies very well. On a bass, the octave shifting mode (Octave Up/Down) is massive. On a monophonic analog keyboard, it allows you to create rich chords from a single key.
