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. Fuzzrocious has 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, they 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.
