A glitch and synth pedal that strips the frequency resolution out of your guitar signal and resynthesises it as resonant oscillations.
Watch
Pedal of the Day's demo covers the spectral decomposer and its glitch-synth output, which is the place to judge whether the effect suits your playing.
Why it matters
The spectral decomposer algorithm lowers the frequency resolution of the input and rebuilds it as oscillations: ATOMS sets how many are produced, SPEED sets how often they refresh, and MODE toggles a sharp or smooth transition. Gearnews named it the most creative pedal of 2025, and it arrived in November 2025. USA MAP is $129 (September 2026) against a $171.60 MSRP, and a power supply is included.
