Electro Harmonix Pico Shimmer Cosmic Reverb Pedal

The Pico Shimmer from Electro Harmonix shrinks a cathedral-sized reverb engine and dual pitch-shifting algorithm into a compact stompbox that measures 93.5 mm wide. This pedal generates octave-up shimmer textures by layering detuned pitch voices over a lush reverb tail, controlled by three top-mounted knobs that adjust pitch interval, reverb decay time, and wet/dry blend. True bypass switching preserves signal integrity when disengaged, while the all-analogue dry path keeps the core guitar tone unaffected by digital processing. The Blend knob governs the balance between the dry signal and the effected shimmer layer, ranging from subtle ambient wash to full wet cathedral sounds. Decay time extends from short room reflections to infinite freeze-style sustain that holds the reverb tail indefinitely. The Pitch control selects intervals including +1 octave, +2 octaves, and major third options, allowing players to dial in anything from angelic single-octave shimmer to stacked harmonic clusters. Standard 9V DC centre-negative power supply operation draws 65 mA, and rear-panel quarter-inch input and output jacks maintain compatibility with any pedalboard signal chain.
