Electro-Harmonix Pico Shimmer Cosmic Reverb

Electro-Harmonix · pedal

The Electro-Harmonix Pico Shimmer is a compact shimmer reverb pedal from Electro-Harmonix in the Pico mini format, delivering shimmer reverb that adds a pitch-shifted harmonic shimmer to the reverb tail for an ethereal, cosmic reverb effect. Controls include Blend (wet/dry), Size (reverb time), and Shimmer (shimmer intensity) in a mini Pico enclosure. The shimmer effect adds an octave-up shimmer layer within the reverb tail.
