Electro-Harmonix Pico IHM Intelligent Harmony Machine - Compact | No Limit Guitar Co, Idaho Falls
The Electro-Harmonix Pico IHM packs the full diatonic harmony power of the legendary Intelligent Harmony Machine into EHX's smallest chassis — delivering silky smooth 2- and 3-part harmonies with lightning-fast tracking that keeps pace with even the speediest lead lines. Ten interval modes, a dedicated MIX knob, and a simple KEY + # button system for key selection make it one of the most intuitive harmony pedals available in a pico-sized footprint. For guitarists at No Limit Guitar Co in Idaho Falls who want a capable pocket sideman without sacrificing pedalboard real estate, the Pico IHM is the answer.
Product Overview
The Pico IHM generates diatonic harmonies in any key, producing pitch-accurate harmony voices that follow the correct scale tones of your chosen key rather than fixed interval shifts — the result is harmony that sounds musical and intentional rather than mechanical. Setting the key is straightforward: the KEY knob and # button work together to select from all 12 keys, and once set, the pedal automatically produces the correct diatonic harmony notes as you play. The INTERVAL control selects from 10 harmonic interval options, spanning a range of harmony configurations from tight unison-adjacent voices to wide, sweeping intervals.
For players who want to go beyond 2-part harmony, holding down the # button activates Dual Mode — adding a second harmony voice for stunning 3-part harmonies when blended with the dry signal. The MIX knob provides precise control over the wet/dry balance, allowing you to dial in anything from a dense, harmony-rich wash to subtle harmonic texture sitting just beneath your lead tone. The VOL knob sets overall output level independently of the mix, keeping your signal consistent when engaging the pedal mid-performance.
Tracking speed is one of the Pico IHM's standout qualities — the pedal keeps pace with fast licks, rapid scalar runs, and aggressive lead playing without lag or pitch artifacts that slower harmony algorithms can produce. A buffered bypass design maintains signal integrity across long cable runs, and the included power supply means it's ready to drop onto any pedalboard right out of the box. At just 2" x 2" x 2.65", it's the most compact harmony machine EHX has ever built — and a genuine workhorse for any Idaho Falls guitar shop player who performs lead guitar.

Key Features
Diatonic Intelligent Harmony Unlike fixed-interval pitch shifters, the Pico IHM generates true diatonic harmonies that follow the correct scale tones of your selected key — producing musical, in-key harmony voices that sit naturally in a band mix.
10 Interval Modes Ten selectable harmonic interval options give players a wide range of harmony configurations to explore, from close voicings to wide-interval arrangements, all accessible via the front-panel INTERVAL control.
Dual Mode — 3-Part Harmonies Holding the # button activates Dual Mode, adding a second harmony voice to the output for full 3-part harmonies when blended with the dry signal — giving a single guitarist the harmonic presence of a three-piece vocal or guitar stack.
Lightning-Fast Tracking The Pico IHM's processing speed keeps pace with the fastest lead lines and scalar runs, delivering tight, accurate harmony without the lag or smearing that slower harmony algorithms produce.
MIX Knob & Buffered Bypass The dedicated MIX knob provides precise wet/dry blending from full harmony wash to subtle harmonic texture, while buffered bypass keeps signal strong and clear across long cable runs.
