Here's what Fairfield Circuitry say about the Unpleasant Surprise Fuzz

Reminisce about the time you got your shoulder caught in the reciprocating saw while this unit destroys your slick jazz lines. The fruit of an oddball circuit, hanging there awkwardly by some parasitic effect. Tweaked, bended and shoe-horned to optimize it’s stench, it’s un pleasance. The time has come to turn all dynamics to s**t! Strangely, it feels very natural.

As The Unpleasant Surprise turns your playing style upside down, you’ll be thankful for its ability to push you outside the box, outside your comfort
zone, all the while retaining the essence of what is played. The artefacts created by this pedal are strange, harsh and unusual but never seem misplaced or out of context.

Using the Unpleasant Surprise

The VOLUME control is self-explanatory. Unity gain is around noon but who cares. Use it to slam your amp or the next pedals in line. Turn it down if the anguish is overwhelming.

The ONSET control affects interstage gain, which happens to mimic an inverse gate threshold. Turn it up for more saturation, longer sustain. Down for spluttery ad-lib f*rts.

T – Simple output treble cut.

G – Affects amplifier bias. Open or Saturated. Allows variations in distortion grain. Note: the difference becomes less noticeable as the ONSET is turned up.

C – Feedforward. Crushes your signal to shit. ONSET controls the amount of compression.

Notes on Powering

The Unpleasant Surprise was designed to operate and sound good using your typical center negative, regulated 9-9.6 VDC power supply. Running it at higher voltages is not desirable nor recommended. There is no battery connection inside the pedal. Always check your power supply for proper voltage and polarity before connecting.

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

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.
