Mammouth Machine Octarat


Mammouth Machine

Adds Distortion to your signal and then duplicates it two octaves down for a huge subterranean tone. 

The Octarat is a fantastic distortion/octaver with a wide range of sounds, there's a ton of fun and chaos to be had here. 

It works really well for both guitar and bass.


  • G(Gain): Adjusts the gain level. 
  • T(Tone): Rolls off brittle high-end frequencies, producing a darker tone. 
  • V(Volume): Adjusts the overall volume level. 
  • D(Direct): Blend of your original tone and the effect. 
  • O(Octave): Set the octave.


  • Standard 9 volt boss type power supply. 
  • 1/4" input and output jacks 
  • True Bypass 
  • No internal battery clip 
  • CNC etching finish.
