A compact version of EHX's Intelligent Harmony Machine, the Pico version generates two-part or three-part harmonies in any key, with fast tracking and low latency. Supplier's Notes: Packing the powerful diatonic functionality of the Electro-Harmonix Intelligent Harmony Machine into an ultra-compact pedal: it's the Pico IHM. Create 2 or 3-part harmony in any key with silky smooth operation and lightning fast-tracking to keep up with any speedy lick. With 10 Interval options, a MIX knob for precision voice blending and space-saving footprint, the Pico IHM is the perfect pocket sideman. Housed in Electro-Harmonix's pico-sized chassis, the Pico IHM comes complete with a simple control set. The KEY knob, in conjunction with the # button sets the key of the harmonies produced. INTERVAL selects from one of 10 harmonic interval options. The MIX and VOL knobs adjust the wet/dry mix and output volume respectively. Holding down the # button enters Dual Mode which adds a second voice to the harmony produced for stunning 3-part harmonies when mixed with the dry signal. The Pico IHM is Electro Harmonix's most compact Harmony Machine ever. Adding perfect, tight harmonies to your playing has never been easier!
