Animal Factory – Pit Viper II

If the original Pit Viper was a venomous beast, the Pit Viper II is a full-on sonic predator. Animal Factory has taken their cult-classic distortion circuit and rebuilt it for Eurorack, packing in even more gain, tonal control, and flexibility. The result? A module that doesn’t just distort. It gnaws, growls, and screams.

At its core, Pit Viper II stays true to its predecessor’s aggressive character but with a touch of extra heat. The unattenuated output feeds directly into a 6 dB state-variable filter, borrowed from the Bonesaw module, adding an entirely new layer of tone-shaping. Lowpass, bandpass, and highpass outputs each have their own volume knobs, allowing for seamless blending and sculpting of the distorted signal.

The real magic happens when you start playing with the filter’s sweepable midpoint and resonance controls. Need something sharper? Crank up the FM knob for even more bite and harmonic chaos. Whether you want snarling bass tones, searing leads, or glitchy, resonant madness, Pit Viper II delivers a wide range of distortion flavors.

With its brutal gain structure and added filtering capabilities, the Pit Viper II isn’t just a distortion module, it’s a complete sonic mangler. If you’re looking for something to inject pure venom into your Eurorack setup, this is it.

Animal Factory – Coma Reactor II

The Coma Reactor II isn’t trying to be clean, polite, or transparent, and thank god for that. This is a delay module that thrives in the grime, delivering lo-fi echoes, feedback-laced chaos, and mangled textures that feel more alive than pristine.

Building on the legacy of the original Coma Reactor, version II takes everything that made the first one weird and wonderful and dials it in just a little tighter. It’s a characterful stereo delay designed to add warble, wobble, and unexpected twists to your modular patches.

What sets the Coma Reactor II apart is its hands-on playability. This isn’t a set-it-and-forget-it delay. It wants to be touched, tweaked, and pushed into self-oscillation. The delay time can be warped in real-time for pitch-bending tape-style artifacts, and the feedback path is more than capable of spiraling into noisy, musical mayhem.

Used subtly, it can add a dusty, analog vibe to your sounds. Used aggressively, it becomes a chaotic instrument in its own right – perfect for experimental setups, feedback junkies, and anyone chasing that sweet spot where control starts to slip.

Paired with a stereo FX loop like the one on the Tannhäuser Gates, the Coma Reactor II shines even brighter. It doesn’t just process your sound – it transforms it.

Animal Factory – Bonesaw

The Bonesaw is not your average polite, well-mannered state-variable filter. No, this thing growls. It shrieks. It self-modulates like it’s possessed. Built by Animal Factory Amplification, the Bonesaw SVF is a stereo-capable filter designed for those who like their filtering with a side of sonic violence.

At the heart of Bonesaw is a classic state-variable architecture, offering lowpass, bandpass, and highpass outputs – but don’t let the traditional design fool you. This filter was made to be pushed. Crank the resonance and you’ll find yourself in the land of feedback and chaos. Engage self-FM, and suddenly the filter becomes an oscillator, a noise generator, and sometimes an unpredictable monster (in the best way possible).

Bonesaw’s strength lies in its ability to handle subtle tone-shaping just as well as it handles full-blown distortion freakouts. Modulating the cutoff and resonance with fast, aggressive CV yields gnarly textures, glitchy sputters, and broken-radio weirdness. Or keep it clean and tight, and it’s a beautifully sculpted tone filter with surgical precision. Your call.

It pairs especially well with distortion-heavy voices (like the Pit Viper II), carving out space or turning your sound into something entirely new. Stereo operation? Check. Flexible routing? Check. Personality? Absolutely.
