The Cat King, formerly known as Rat King, by Fuzzrocious Pedals, is the “king sized” version of Fuzzrocious Pedals Cat Tail, a low to high gain distortion with overdrive capabilities.  Some say, at high gain settings, the Fuzzrocious Pedals Cat Tail sounds like a fuzz.

The Fuzzrocious Pedals Cat Tail circuit is based on a well loved classic distortion that make a clean amp dirty and a dirty amp disgusting.  Fuzzrocious Pedals 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, Fuzzrocious Pedals 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.


Fuzzrocious Pedals have a range of modifications available, e.g. types of paint/art, enclosure colour and circuit mods.  Please see the Fuzzrocious Pedals website for details

If there is a modified Fuzzrocious Pedal you require, we will gladly order it on your behalf.  For details and a price, please email us via


  • Volume: Makes the output of the circuit louder or quieter
  • Tone Filter: Moves from treble to bass when turned clockwise.  There is a general high mids presence in most tone settings with little to no bass loss.
  • Distortion 1 & 2 Pots: Moves from a little to no drive/distortion to high distortion when turned clockwise.
  • Clipping 1 & 2 Pots: Fine tunes how the signal clips on the highs and lows. To start, roll them both back, then slowly roll them clockwise to find your personal taste in clipping of your signal.
  • Diode Toggle: Connects to the Diode pot to blend between 1n914 silicon diodes and LEDs.  Toggle up means the diodes are active; down means no diodes are active (less compressed, more open sounding).
  • Diode: See explanation in “DIODE TOGGLE” above
  • Feedback: Connects to the feedback footswitch to control the feeding back of the circuit’s signal into itself to let you makes lots of noise.
