A Radical Approach to Synthesis Inspired by Lo-Fi Aesthetics
The " Atomic Cluster Spectral Decomposer " follows in the footsteps of experimental digital effects, combining granularity, bit reduction and resonant synthesis. Rather than being a simple clone of a classic, it deconstructs the signal at its source in order to recompose new, musical and surprising textures.For Texture Creators, from the Studio to the Stage
Designed for guitarists, bassists and keyboard players seeking soundscapes, it excels in ambient, experimental indie, electro, post-rock and soundtrack applications. On stage, it brings rhythmic patterns and atmospheric layers; in the studio, it proves to be an inspiring tool for sound design and original overdubs.Intelligent Controls and Expressive Modes
" ATOMS " sets the number of simultaneous oscillations to make the spectrum denser or more open. " SPEED " adjusts the algorithm's refresh rate and can also be controlled via tap tempo to synchronize your patterns. The " MODE " knob switches between " SHARP " oscillation transitions (more defined) and " SMOOTH " transitions (more fluid). " VOL " controls the output level. 6.35 mm jack input/output for easy integration into your pedalboard.The Sound
Its character shifts between musical granulation and organic synthesis. The response is dynamic: the harder you play, the denser the oscillations become, generating mechanical arpeggios, hypnotic sequences or silky pads. In " SHARP " mode, the grain is incisive and glitchy; in " SMOOTH " mode, the transitions become velvety, perfect for evolving pads and warm drones.Technical specifications

Questions frequently asked
Which instruments can be connected to this pedal?
The connections use 6.35 mm jacks for input and output. The pedal is designed for guitar, bass, and keyboards.
Electro Harmonix Pico Atomic Cluster Spectral Decomposer: can the SPEED be synchronized?
The SPEED control adjusts the refresh rate of the algorithm. A tap tempo function allows controlling this speed. Patterns can thus be synchronized with playing.
What is the difference between SHARP and SMOOTH modes?
The SHARP mode produces sharper, glitchier oscillation transitions, while SMOOTH favors fluid transitions for pads and drones.
What power supply and consumption does the pedal require?
The power supply is mains type. The indicative consumption is 150 mA.
What is the purpose of the ATOMS setting?
The ATOMS setting determines the number of simultaneous oscillations. It allows densifying or opening up the spectrum generated by the digital effect.
