Electro-Harmonix Intelligent Harmony Machine (IHM)

• Intelligent Harmony Mode: Generates single-note, diatonically correct harmonies based on a selected musical key. If you set the key to C Major and choose a third above, playing a C note produces an E (a major third), while playing a D note automatically produces an F (a minor third) to stay perfectly in key. 
• Polyphonic Override Mode: Disengages the key tracking to act as a full polyphonic pitch shifter, much like the classic EHX Pitch Fork . This mode allows you to shift the pitch of entire chords or single notes simultaneously, perfect for electronic drop-tunings or simulated baritone guitar tones.

• Key Selection: A dedicated rotary knob alongside a #/- switch and a Major/Minor switch allows you to quickly dial in any of the 12 musical keys.
• 11-Position Interval Selector: Offers 11 unique settings per mode, spanning simple intervals (such as thirds, fourths, and fifths) up to sophisticated three-part configurations like "3rd Up + 5th Up" or "5th Up + Octave Up".
• Momentary Mode: Holding down the footswitch engages the effect dynamically, with an adjustable pitch sweep time controlled by the Volume knob.
• Dual Outputs: Features a standard main output and a dedicated Dry Out jack. This allows you to split your signal into a stereo-like setup, sending your unaffected dry guitar tone to one amplifier and the harmonized signal to another.
