The Nantel Verdict
The Nantel Verdict
Shimmer reverb with pitch-shifted harmonics; integrated modulation and delay layers; compact form factor with deceptively deep parameter control; built on EHX's proven Oceans Reverb architecture scaled for pedalboard real estate.
Compact footprint suits tight setups; stereo output recommended for full spatial character; modest learning curve to unlock deeper sound design; pairs well with expression pedals for dynamic modulation control.
A gateway to soundscape creation that justifies its price through sonic depth and creative possibility. Essential for players seeking atmospheric texture beyond conventional reverb, without sacrificing pedalboard space.

Pico Shimmer
Cosmic Reverb
Explore another world of reverb with the EHX Pico Shimmer!
Channeling ethereal inspiration from otherworldly celestial structures and far-off galactic formations, the EHX Pico Shimmer is a supersonic traveler to the swirling, gleaming edges of ambience. Building on Shimmer concepts from the award-winning Oceans Reverb pedals, this compact device transforms your instrument into an immersive soundscape machine. Harnessing the powers of reverb, modulation, delay, and synthesis, you will discover a whole new world of fresh spatial exploration.
The Pico Shimmer features 3 shimmer reverb Scenes: The classic Intergalactic, the mellow Off-World, and the glitchy Etherdust.
INTERGALACTIC
A classic shimmer made up of polyphonic octaves, reverb, modulated delay and compression with the addition of a string synthesis engine. Morph between plate reverb, classic shimmer, and ethereal strings to create cinematic atmospheres beyond time and space.
OFF-WORLD
A smoother, mellower shimmer effect with enhanced delay modulation. Vintage synthesizer textures abound and lift Off-World to an orbiting atmospheric soundscape.
ETHERDUST
A glitch shimmer effect where the delay time is randomized, creating stutters ranging from short granular sparkles to distinct glitch echoes.
Controls on the Pico Shimmer are simple but powerful with Secondary Knob Functions available. BLEND adjusts the overall wet/dry blend while TONE controls the overall brightness of the effect. TIME sets the decay time with infinite reverb available when maxing out this control. The VOICE knob morphs the effect between clean plate reverb, classic shimmer, and ethereal string effects for dialing in precise flavors of ambience. The SCENE button toggles through the three modes as well as engages the Secondary Knob Functions with a press and hold. These secondary functions include adjustments to reverb mix, delay time, and modulation depth and rate. Access Infinite Reverb on the fly for momentary pad-like effects by pressing and holding the footswitch.
