“One year ago, we released the very unique Octa Psi. Today, we celebrate our 24th anniversary by modding our own pedal! The Taiga Edition features a massive overhaul of the fuzz circuit, meticulously re-engineered with 20 component changes to capture the iconic sound of the Green Russian Big Fuzz. Get the legendary, thick mids and focused lows you’ve been craving, with more dynamic range to dial in everything from saturated doom to classic overdrive. “The pitch-shifting perfection you love in the OG Octa Psi, remains untouched. I love the new Taiga and it’s the perfect reason to have two in my signal chain!” – Robert Keeley

Distortion

Distortion pedals take your clean guitar signal and transform it into something bigger, bolder, and full of attitude. By clipping the waveform, they add sustain, bite, and aggression, creating that thick, compressed tone that’s powered rock music for decades. From the growling crunch of classic hard rock to the tight, saturated roar of modern metal, distortion is all about energy and presence. It gives every note weight and authority, pushing your amp to its limits and beyond.

There are countless flavours of distortion, each with its own texture and edge. Some sound smooth and creamy, others raw and gnarly like tearing fabric. It’s the sonic equivalent of turning up the heat until the sound cooks — rich, sizzling, and perfectly seasoned to taste. Whether used for rhythm muscle or soaring leads, a good distortion pedal doesn’t just add volume; it adds personality, grit, and that unmistakable sense of power under your fingers.

Expression

Expression pedals allow real-time control over specific parameters on compatible guitar pedals, such as volume, delay time, modulation depth, or filter sweep. Used with an expression input, they let players shape effects dynamically with their foot, adding movement and performance control that cannot be achieved with fixed knob settings.

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.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Overdrive

Like a golden layer of melted cheese — warm, gooey, and just put it all over. It adds just the right amount of richness and grit, turning a clean signal into something smooth and savoury. Designed to mimic the natural breakup of a tube amp pushed to its sweet spot, overdrive delivers the flavour of classic rock and blues in every bite. From creamy mid-gain warmth to crisp edge-of-breakup sparkle, it’s the comfort food of guitar tone — simple, satisfying, and endlessly versatile. Whether it’s a mild crunch or a full-bodied roar, overdrive is where good taste begins.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
