The GREY STACHE is based upon the GGG-tuned and Civil War versions of a muff fuzz, creating one versatile guitar AND bass-friendly monster! The tone stack features the ability to scoop mids to allow a heavy, deep sound, flatten the mids for an even-keeled sound, or boost the mids for a more modern sound that allows one to punch through in the mix and drive speakers well. It’s more than just a fuzz in that if you dial back the sustain, one can achieve more of an overdrive sound.

Grey Stache

The Cat Tail is a low to high gain distortion with overdrive capabilities (some even say at high gain settings, it sounds like a fuzz). This
circuit is based on a well-loved, classic distortion that make a clean amp dirty and a dirty amp disgusting. We have tweaked the original
circuit to better meet the needs of guitarists and bassists alike. With the addition of a diode toggle for extra tweakability for clipping
options, we have added to the modifications the Beavis double resistor mod (Clipping 1 and 2 pots) to allow the user to subtly fine tune
how the signal clips on the highs and lows.

Cat Tail

Der Big Fella vereint Overdrive, Distortion, Gate‑Fuzz und Feedback in einem kompakten 1590BB‑Gehäuse. Er lässt sich mit 9–18 V DC (center‑negative) betreiben und bietet dadurch erhöhten Headroom und mehr Klarheit. Der Gate‑Fussschalter aktiviert eine synthähnliche Fuzz‑Gate‑Funktion, ideal für Palm‑Mutes oder abrupte Sounds. Ein oben platzierter Momentary‑Feedback‑Schalter löst direktem Chaos mittels Feedback‑Regler und internem Trimmpoti aus. Ein Modusschalter wählt zwischen Demon (Volume, Tone, Drive) und Li’l Fella (zusätzlicher Gain‑Regler und wärmerer Klang) Modi. Alle Anschlüsse sind oben angeordnet für platzsparenden Pedalboard‑einsatz.

The Big Fella combines overdrive, distortion, gated fuzz and feedback in one compact 1590BB enclosure. Its architecture allows operation at 9–18 V DC (center‑negative), offering extended headroom and clarity. A Gate footswitch engages a synth‑like fuzzy gate ideal for palm‑mutes or abrupt silence. A top‑mounted momentary Feedback footswitch triggers controlled chaos via a dedicated Feedback knob and internal trimmer. A mode toggle switches between Demon (basic Volume, Tone, Drive) and Li’l Fella (adds Gain and a warmer tone stack) voicings. All jacks and power are top‑mounted for pedalboard efficiency.

The Cat King is the “king sized” version of our Cat Tail, a low to high gain distortion with overdrive capabilities (some even say at high gain settings, it sounds like a fuzz). This circuit is based on a well-loved, classic distortion that make a clean amp dirty and a dirty amp disgusting. We have tweaked the original circuit to better meet the needs of guitarists and bassists alike. With the addition of a diode toggle for extra tweakability for clipping options, we have added to the modifications the Beavis double resistor mod (Clipping 1 and 2 pots) to allow the user to subtly fine tune how the signal clips on the highs and lows.
