Electro-Harmonix’s new Pico Shimmer packs cosmic reverb into a compact stompbox

The Pico Shimmer includes three scenes, infinite reverb on tap and a string synth engine – all in EHX's iconic compactly designed pedal.

Electro-Harmonix has expanded its Pico line with the Pico Shimmer Cosmic Reverb, a pocket-sized pedal built around three effect scenes: Intergalactic, Off-World and Etherdust. Each draw on reverb, delay, modulation and an octaves and string synth engine.

Catch up on all the latest news here.

Intergalactic is the most traditional of the three, blending polyphonic octaves, reverb, modulated delay and compression with a string synthesis engine for cinematic shimmer textures. Off-World is smoother, with vintage synth-style ambience and enhanced delay modulation for warmer, pad-like sounds. Etherdust takes things furthest from conventional shimmer, with randomised delay times covering everything from subtle granular sparkle to pronounced glitch echoes.

Most of the heavy-lifting is dealt with by four knobs. Blend sets the wet/dry mix, Tone adjusts overall brightness and Time controls decay from short reverb through to infinite sustain. The Voice knob is where the character shifts – you can morph between plate reverb, classic shimmer and string synth pad depending on how far you want to go. The Scene button cycles through the three modes, and holding it down opens a secondary layer for adjusting reverb mix, delay time, and modulation depth and rate without adding extra controls to the chassis.

When it comes ot live use, holding the footswitch triggers Infinite Reverb on the fly, freezing the current note or chord into a continuous pad. Three buffered bypass modes – Digital, Analogue and Hybrid – give players control over how the pedal sits in a signal chain and whether reverb trails fade naturally on bypass.

The Pico Shimmer ships with a 9V power supply included and is available now.
