Electro-Harmonix Pico Atomic Cluster - Spectral Decomposer

Open Box Unit

Electro-Harmonix Pico Atomic Cluster - Spectral Decomposer.

Transform your sound at the molecular level with the Atomic Cluster Spectral Decomposer. This compact glitch-and-synth pedal breaks your signal into resonant oscillations, reshaping your playing into rhythmic lo-fi artifacts, animated arpeggios, or lush ambient pads. Powered by a unique frequency-reduction algorithm, it opens the door to textures that are musical, strange, and completely new.

Key Features

• Unique Frequency-Reduction Algorithm: Reduces the resolution of your input signal to generate oscillations directly tied to your playing, producing glitchy, synth-like tones.

• ATOMS Control: Adjusts how many oscillations are active at once — from a full spectrum for natural sounds down to a single oscillation for pixelated, glitch-heavy effects.

• SPEED Control with Tap Tempo: Sets how quickly oscillations refresh. Slow speeds mimic step-filter rhythms; fast speeds create unpredictable, chaotic movement.

• SHARP / SMOOTH Modes: SHARP delivers instant transitions for tight rhythmic effects; SMOOTH blends each oscillation for a fluid, ambient character.

• VOL and BLEND Controls: Shape your overall output level and dial in the perfect wet/dry mix.

• Power Supply Included: Ready to use right out of the box.
