Electro-Harmonix Pico Atomic Cluster Pico Atomic Cluster | Spectral Decomposer The Electro-Harmonix Pico Atomic Cluster Spectral Decomposer is a powerful and highly specialized digital effects pedal that provides musicians and sound designers with an innovative tool for deep sonic transformation. Housed in the compact, pedalboard-friendly Pico chassis, this device employs a unique algorithm to deconstruct an instrument's tone to an atomic level, deliberately reducing the frequency resolution of the incoming signal. Unlike conventional modulation or time-based effects, the Atomic Cluster generates a series of resonant oscillations directly related to the input source, interpolating the sound into a variety of compelling musical and whimsical textures. The result is a diverse range of effects, spanning from rhythmic, lo-fi glitch and structured auto-arpeggio patterns to expansive, ambient synth pads. The core of the pedal's functionality is managed through two key controls: ATOMS and SPEED. The ATOMS knob governs the quantity of simultaneous resonant oscillations that are produced, essentially controlling the spectral density and "pixelation" of the effect. By reducing the ATOMS setting, the pedal moves from a full spectrum close to the original instrument sound toward a more reduced, glitched, and rhythmically fragmented output. The SPEED knob adjusts the refresh rate of the underlying oscillation algorithm, determining the temporal character of the decomposition. Slower speeds can create a stepped, rhythmic step-filter sound, while faster settings allow for more volatile, chaotic, and randomized effects. For musicians who require exact rhythmic integration, the SPEED parameter can be quickly set via tap-tempo, making it an effective tool for both studio and live performance applications. Adding further flexibility to the sonic sculpting is the MODE button, which allows the user to select the transition envelope shape between the resonant oscillations. The SHARP mode provides an instant, immediate transition that is ideal for generating distinct, percussive, and rhythmic results. Conversely, the SMOOTH mode utilizes a gradual, faded envelope, resulting in a more lush, ambient, and seamlessly transitioned effect, particularly suitable for creating deep, sustained atmospheric washes. Comprehensive control is maintained through the VOL knob for output leveling and the BLEND knob, which offers a full sweep from 100% dry to 100% wet, enabling precise mixing of the effect with the original instrument tone. The Pico Atomic Cluster is a testament to Electro-Harmonix's commitment to pushing creative boundaries, offering guitarists and synth players a miniature machine capable of vast sound design.
