The Fuzzrocious Cat Tail Distortion is a very high gain distortion and overdrive pedal based around the circuity of the legendary ProCo Rat pedal keeping both guitarists and bassists' tones in mind. Additional features and modifications such as a switchable diode for clipping options, there is also a resistor mod to allow for further fine tune control of the clipping of both lows and highs. 

Note: This pedal is formerly known as the Rat Tail, it is in fact the same circuit with a different name.
