Rabbit Hole FX Chaosmic Fuzz


Rabbit Hole FX

It is with warm fuzz's that Rabbit Hole FX presents the Chaosmic Fuzz. The result of a rare collaboration of talent, ideas and dedication, the Chaosmic Fuzz was inspired by an obscure circuit from the 1960's (Hint: The Scrambler) and updated using radical and modern design methods allowing for greater flexibility and control of a well-loved but limited classic.

Our goals were clear from the start: to create a highly versatile octave fuzz pedal that offers precise control and that works with any instrument. Big sound in a small enclosure with features that discerning players demand. These goals were not only accomplished but exceeded. It's all here: super fat growling synth fuzz, ripping upper-octave riff-inspiring thick fuzz and chaotic inter-modulating sonic destruction... all the while being highly sensitive to playing dynamics and remaining free of noise.

Six controls allow precise, fine-tuning to your instrument and rig:

  • Gain - Wide range of gain on tap; from mild to over-the-top
  • Chaos - Morphs from dynamic growling fuzz tones all the way to searing upper-octave inter-modulating madness
  • Level - Fuzz signal volume
  • Low - from the thin, maddening buzz of mosquitoes to the terrifying resonance of a swarm of giant hornets
  • High - from deep, dark fuzz to scalpel-sharp piercing tones that cut through the biggest band and loudest mix 
  • Clean - Clean signal volume


  • Top-mounted input/output/power jacks
  • Industry standard 2.1mm, 9V DC power requirement (center negative)
  • Small 125B sized pedalboard friendly enclosure
  • Durable and high resolution DTS (direct to substrate) labeling and art
  • Carling soft-switching relay-based True Bypass footswitch
  • Violet LED indicator with internal trimmer to adjust LED brightness
  • High quality parts used throughout for reliability, durability and  noise-free performance
  • Black satin multi-purpose swag bag.
