DI

A DI pedal (Direct Injection) lets you send your signal straight to a mixing desk or audio interface with clarity and confidence. It converts your instrument’s output into a balanced signal, reducing noise and allowing for longer cable runs without losing quality. Whether you’re playing live or recording, a good DI keeps your tone clean, controlled, and stage-ready.

Use a DI to go direct at a gig, split your signal between amp and PA, or capture a pure track in the studio. It’s a practical, dependable tool that ensures what leaves your pedalboard arrives exactly as intended — solid, noise-free, and ready for the mix.

Filter

A filter pedal shapes your tone by emphasising or cutting specific frequencies, letting you sculpt everything from subtle tonal shifts to bold, sweeping textures. Unlike traditional wah or envelope effects, filters can be static or controlled in different ways, giving you focused control over how bright, dark, sharp, or resonant your sound becomes.

Use a filter to tighten the low end, tame harsh highs, or create synth-like sweeps and rhythmic movement. Whether you’re refining your core tone or pushing into experimental territory, a filter pedal gives you precise control over the flavour of your sound.

Fuzz

A fuzz pedal is one of the earliest and most aggressive forms of distortion, turning your clean guitar signal into a thick, saturated wall of sound. It works by clipping the waveform almost flat, creating a compressed, gritty tone full of harmonic overtones. The result is raw, unruly, and unmistakable — from the sputtering breakup of vintage germanium circuits to the searing sustain of modern silicon designs. Fuzz pedals react strongly to your guitar’s volume and pickup choice, making them dynamic tools for expressive players.

Whether you’re chasing the classic tones of Hendrix and the Smashing Pumpkins or exploring heavy, experimental textures, fuzz remains a favourite for its personality and unpredictability. It can sound smooth and sustaining, or wild and velcro-like, depending on how it’s set up. A good fuzz pedal cuts through the mix while adding thickness and attitude, turning any riff or lead line into something bold and unmistakably alive.

New

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

noise gate

A noise gate pedal keeps your rig tight and controlled by cutting unwanted hiss and hum when you’re not playing. High-gain setups, stacked pedals, and long signal chains can introduce background noise — a noise gate steps in to silence it cleanly, letting your riffs start and stop with precision.

Use it to sharpen heavy rhythm parts, tame buzzing single-coils, or clean up complex pedalboards without sacrificing sustain. Dial it subtle for transparent control or tighter for that sharp, percussive stop-start effect — either way, it keeps your sound focused and professional.

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.
