Created by legendary product visionary Fumio Mieda, the Nu:Tekt HD-S is a build-it-yourself pedal that combines three different distortion circuits to deliver never-before heard harmonic distortion. Create new and as-yet undiscovered sounds — from traditional fuzz, to out-of-this world distorted sounds — by mixing the different distortion circuits. A wide range of sonic possibilities means you can use HD-S with guitars, bass guitars, synths, and more. Anywhere you're looking for new and unique sounds!

One of the hallmarks of the Nu:Tekt Series is that they're assembled by you! The HD-S kit doesn't require soldering, and the necessary tools are included — making it easy to have the enjoyment and satisfaction of creating your own sound, from scratch.

The Power of Three

The HD-S reimagines the distortion pedal, with modulation and filter-like control over your sound. In addition to four control knobs on the panel, you can use three additional trimmer knobs to adjust the balance between each of the distortion circuits for sonic results as tame or as wild as you can imagine.

Easy Assembly

Assemble the HD-S with ease, just like a model kit — no soldering required. All necessary tools are included, along with a circuit diagram in the owner's manual. It's perfect for those who love building their own effect units with top-notch performance and sound.

The Brainchild of Fumio Mieda

Fumio Mieda is a legend of the electronic music world. After creating the Uni-Vibe (most famously used by Jimi Hendrix), Mieda-san was employed by Korg founder Tsutomu Katoh in 1976 and has been responsible for countless innovations since.

In his own words: "As of 2023, 61 years have passed since the first compact effects unit, the Maestro Fuzz-Tone, was released. Even nowadays, distortion-based effects including overdrive and distortion are the mainstay for guitar effects units, and the vast majority of these effects units are simply rehashing the sounds of the past. For this reason, we've developed a new kind of distortion based on harmonic synthesis that covers both traditional and all-new sounds."

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.

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.

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.
