Expand your sonic palette with the Electro-Harmonix Pico Intelligent Harmony Machine, a pocket-sized pedal that effortlessly turns every note you play into rich, musical harmony. With programmable diatonic tracking, 10 interval options and a Dual mode for layering multiple voices, the Pico IHM keeps pace with even the fastest lead lines while adding depth and dimension to your playing. Its intuitive design makes creating two- or three-part harmonies as simple as setting your key and engaging the pedal, delivering professional-grade harmonies in an ultra-compact, stage-ready package.

Lightning-Fast Diatonic Harmony Engine

At the heart of the Pico IHM is a sophisticated diatonic harmony processor that tracks single-note melodies in real time. Each interval produces musically precise harmonies that stay tight and clear, even during rapid passages or complex riffs. Engage Dual mode with the # button to layer a second voice for three-part harmonies, giving your playing cinematic richness and a broader tonal palette. Whether you’re comping, soloing or experimenting with textures, the Pico maintains accuracy and musicality without lag or smearing.

Intuitive Controls for Effortless Blending

The pedal’s simple yet powerful control set allows instant customization of your harmonies. Use the KEY knob in combination with the # button to set your key, INTERVAL to select one of 10 harmony intervals and MIX to dial in the perfect balance between dry and harmonized signals. A dedicated VOL knob ensures the overall output sits naturally in your rig. Every function is designed to be accessible at a glance, letting you focus on musical expression instead of technical setup.

A Compact Harmonizer Built for Any Rig

Despite packing the full functionality of Electro-Harmonix's classic Intelligent Harmony Machine, the Pico IHM lives in an ultra-compact chassis, making it ideal for pedalboards of any size. Mono input and output jacks, a 9.6V DC power supply and low 100mA current draw make it easy to integrate with existing setups. Handheld in size but monumental in impact, the Electro-Harmonix Pico Intelligent Harmony Machine delivers lush, accurate harmonies for guitar, bass or synth—making it the ultimate pocket-sized sideman for creative players everywhere.
