Deconstruct your tone to an atomic level with the Atomic Cluster Spectral Decomposer. Unlike any effect Electro-Harmonix has made before, this compact glitch and synth pedal breaks down your signal and interpolates it into a variety of musical and whimsical sounds. Using a unique algorithm to reduce the frequency resolution of your instrument, it creates a wide range of unique effects from rhythmic lo-fi glitch and auto-arpeggio tones to ambient synth pads and more!

The two main controls on the Atomic Cluster are the ATOMS and SPEED knobs. ATOMS controls the number of simultaneous resonant oscillations sounds at any moment, from a full spectrum of what is being processed down to a single note. With more oscillations, the tone is closer to your input signal. As the control is turned down, oscillations are reduced, creating a more pixelated, glitchier sound. The SPEED knob adjusts how quickly the pedal refreshes the oscillations, allowing you to control the timing and rhythm of the effect. Slower settings can mimic the sound of a rhythmic step filter while faster settings create a more chaotic random feeling effect. SPEED can also be set by tap tempo. Additional VOL and BLEND controls adjust overall output level and wet/dry mix respectively.
The MODE button toggles between SHARP and SMOOTH modes which choose the oscillation transition envelope shape. SHARP creates an instant transition for a more immediate, rhythmic effect. SMOOTH transitions between oscillations gradually, smoothly faded into one another for a more lush, ambient effect.
Quick Specs:
• Unique algorithm to reduce the frequency resolution of your instrument, generating resonant oscillations directly related to your input signal
• ATOMS sets how many oscillations are produced at a given moment
• SPEED Sets how quickly the algorithm refreshes the oscillations it produces. This can also be controlled via tap-tempo
• MODE Button toggles between SHARP and SMOOTH Oscillation Transition modes
• VOL Adjusts the output volume
• Power Supply included
