Designed with Yvette Young

Like tapping? Whacky tunings? Lush stacked-pedal tones that range from crunchy chords to soaring ambient textures? Yvette Young knows what’s up. The Covet band leader has been setting the guitar world ablaze with her signature tones and unique polyphonic style inspired by her piano playing background. She’s also a big Walrus Audio fan. Cue her teaming up with the Oklahoma company to design her own pedal, channelling her love of ambient, glitchy, digital-meets-analog effects.

Chorus

Delay

A delay pedal records your signal and plays it back after a set time, creating echoes that can range from tight, slapback repeats to long, atmospheric trails. It’s one of the most versatile effects, used to thicken tones, add rhythmic depth, or build spacious, ambient layers. Analogue delays offer warm, decaying repeats that blend naturally with your tone, while digital units provide pristine echoes with precise control over time, feedback, and mix levels.

From classic rockabilly and tape-style echoes to modern looping and shimmer effects, delay pedals have become essential tools for shaping sound. They can make solos soar, rhythms pulse, or transform simple chord progressions into cinematic textures. Whether used subtly to add dimension or boldly to create soundscapes, a good delay pedal can completely redefine the feel and atmosphere of your music.

Filter

MIDI

MIDI pedals use the Musical Instrument Digital Interface standard to communicate with other guitar pedals, effects units, and hardware. They allow control over presets, parameters, and switching across multiple devices from a single controller. MIDI integration makes it possible to build complex, synchronised pedal setups while keeping control simple and consistent.

New

This is brand new, fresh in, and a UK warranty is included. New Gear always comes from trusted UK music retailers.

Reverb

A reverb pedal is like the rich sauce that ties every flavour on the plate into one smooth experience. It adds depth, warmth, and atmosphere — the sonic equivalent of a perfectly reduced glaze that lingers on the tongue. Whether you’re after the subtle ambience of a cosy café (spring or plate reverb) or the grand echoes of a cathedral (hall or shimmer reverb), this is where your tone breathes and expands. A touch of reverb can turn a dry sound into something lush and inviting — but pour on too much, and it’s all you can taste. Used with finesse, it’s the finishing touch that transforms your tone from plain to unforgettable.

Synth

A synth pedal transforms your guitar signal into rich, layered tones that mimic the sounds of a synthesiser. Using pitch tracking and waveform generation, it can produce everything from deep bass lines to shimmering pads and futuristic leads. Synth pedals open up a wide creative range, blending the expressiveness of guitar playing with electronic textures, making them ideal for experimental sounds, ambient music, or adding a modern edge to classic riffs.
