The Electro-Harmonix Intelligent Harmony Machine is an exceptionally precise pitch-shifting and intelligent harmony pedal. Capable of generating perfect diatonic harmonies matching your selected key and scale, it instantly creates twin-guitar lead lines, octave textures, or dynamic pitch-bend effects using its Momentary mode.
