Electro-Harmonix Pico Atomic Cluster – Spectral Decomposer & Oscillator Pedal

The Electro-Harmonix Pico Atomic Cluster is a compact oscillator-based effects pedal that radically reshapes your instrument’s signal into glitchy, rhythmic, and synth-like textures. Using a unique spectral decomposition algorithm, it reduces frequency resolution and reconstructs your sound as resonant oscillations, ranging from lo-fi rhythmic pulses to chaotic glitch patterns and smooth ambient pads. Packed into EHX’s Pico format with tap tempo and flexible blending, the Atomic Cluster is a creative sound-design tool—available at Soundium.

Key Features

• Spectral decomposition engine: Breaks down your signal into resonant oscillations derived directly from your input
• ATOMS control: Sets the number of simultaneous oscillations, from full-spectrum tones to single-note glitch textures
• SPEED control with tap tempo: Adjusts how fast oscillations refresh, from rhythmic step-filter effects to chaotic motion
• SHARP & SMOOTH modes: Choose between instant, percussive transitions or gently crossfaded ambient movement
• Blend & volume controls: Dial in the perfect wet/dry balance and output level
• Pico format: Ultra-compact enclosure fits easily on crowded pedalboards

Customer Benefits

The Pico Atomic Cluster opens up entirely new sonic territory for guitarists, bassists, and experimental musicians. It excels at creating rhythmic glitches, auto-arpeggio textures, and evolving synth-like soundscapes without needing external MIDI or synth gear. Tap tempo and blend control make it easy to integrate into both structured rhythmic setups and free-form ambient performances.
