Fairfield Circuitry

Why we like Fairfield Circuitry

Fairfield Circuitry pedals are hand-built in Hull, Québec, and sit in a sweet spot between experimental and genuinely usable. Since the late 2000s they’ve been designing original circuits that explore the edges of sound – K-field modulation, tape-flavoured analogue delay, FM and ring modulation, parametric EQ, active feedback loops – but always with a strong musical core. The housings are understated, the sounds are anything but.

Shallow Water & Meet Maude – Lo-fi Modulation & Analogue Delay

Shallow Water is Fairfield’s cult “K-Field Modulator”: it starts from an analogue chorus/vibrato circuit, then randomly modulates a short delay time to create non-cyclical pitch shifts. The result is a lo-fi, warbly vibrato/chorus/flanger that feels like old, slightly broken tape – perfect for subtle movement, lush ambience or completely seasick textures on guitar, bass or synths.

Meet Maude is an analogue delay voiced like a worn reel-to-reel machine. Dark repeats, natural compression and subtle pitch wobble sit your echoes underneath the dry signal rather than on top of it. It’s equally at home as a subtle slapback, a dubby rhythmic delay or a washed-out, almost reverb-like ambience, with the feedback and tone controls giving a wide range of “old tape” flavours.

Barbershop Millenium & Modèle B – Always-On JFET Overdrive

Barbershop Millenium is a modern classic: an original JFET overdrive with flat, wide frequency response and a very natural clipping character. It’s designed to behave like a pushed amp – touch sensitive, dynamic and not overly compressed. The Drive, Sag and Volume controls plus the three-position tone switch let you move from barely-there grit through to rich, harmonically complex overdrive while still sounding like your guitar and amp.

Modèle B takes the Barbershop circuit and puts it in a tiny, “always on” format – no footswitch, no LED. Inside, a jumper lets you choose between flat/wide response or a light high-frequency roll-off. Drive, Sag and Volume behave like the Barbershop: you can use it as a foundation tone/“preamp” that lives at the front of your board, from cleanish enhancement to chewy, amp-like crunch, then shape the final top end at your amp or with an EQ.

The Accountant – Compact JFET Compressor

The Accountant is a tiny, all-analogue JFET feedback compressor with a fixed 5 ms attack and 500 ms release. PAD and RATIO set how hard the compressor works, while VOLUME brings the level back up. It can do barely-there levelling for clean guitar, bass or keys, or heavy squish and added harmonic grit for more obvious compression. It’s simple, fast to dial in, and works across guitars, bass, synths and even mixes without eating board space.

900 & The Unpleasant Surprise – Fuzz & Gated Chaos

900 – About Nine Hundred is a highly versatile fuzz based around a mu-amp input stage and a second JFET gain stage. INPUT controls how hard you hit the circuit, FUZZ and BIAS interact for everything from gritty drive to thick, saturated fuzz and gated textures, and VOLUME has loads of output on tap. It stacks well with other pedals and is genuinely happy with guitar, bass and other instruments.

The Unpleasant Surprise is an experimental fuzz and noise gate with an unapologetically aggressive voice. Volume and Onset controls plus Gain/Treble/Crush switches give you splattery, ripping fuzz tones that clamp down hard when you’re not playing, for violent stutters, chopped-off sustains and synth-like gating. Perfect if you want something far nastier than a classic fuzz, but still intuitive to use.

Randy’s Revenge & Roger That – Ring Mod & FM Degeneration

Randy’s Revenge is an all-analogue ring modulator with a pure sine wave carrier and a wide frequency range. At low frequencies it can work as a rich, tremolo-like effect; as you push the carrier up you get classic clangy ring-mod sounds, inharmonic overtones and bell-like textures. A flexible control set lets you go from subtle animation to completely alien tones, and it’s very usable on guitar, bass, keys or modular gear.

Roger That is a simplified FM modulator/demodulator designed to mimic the sound of a failing AM/FM radio. With TUNE, SHIFT, DRIVE, WET/DRY and range/filter switches (plus CV on Tune), it moves from subtle broadcast-style grit and bandwidth-limited filtering to extreme signal degradation, noise, pops, crackles and squeals. It’s ideal for textural sound design, noisy interludes and making otherwise “polite” rigs sound broken in a very deliberate way.

Long Life & Hors d’Oeuvre – Modular-Style Utilities on a Pedalboard

Long Life is a single-band parametric EQ and state-variable filter with some modular-style extras. FREQ, Q, GAIN, TILT and VOL let you set anything from gentle tone shaping to aggressive resonant sweeps and self-oscillating filter tones. CV inputs for frequency and resonance, V/oct scaling and an expression input mean it can act as a filter, EQ, or even a VCF/VCO-type voice in a modular-style setup, as well as a very powerful tone tool in front of or after other pedals.

Hors d’Oeuvre? is an active feedback loop and mixer that opens up a lot of creative routing tricks. With FET preamps, phase selection, DRY/WET/FEED controls and two outputs, you can create positive or negative feedback loops around other pedals, mix dry and effected paths, split or combine signals, build no-input drones and explore all sorts of unstable behaviours. It’s part utility, part noise-machine – especially fun with delays, reverbs, ring mods and pitch shifters.

Together, these Fairfield Circuitry pedals cover everything from always-on foundation tone (Barbershop & Modèle B) and compact compression (The Accountant) to experimental modulation (Shallow Water, Meet Maude), fuzz (900, Unpleasant Surprise), filtering (Long Life) and outright sonic destruction (Randy’s Revenge, Roger That, Hors d’Oeuvre?).
