Jackson Audio Large Mouse Distortion Module for Asabi Pedal

Written by

Elliot Stent

The 'Large Mouse' module is a fully-analogue distortion module for the Jackson Audio Asabi Mateus Asato signature distortion/overdrive pedal. This replaces the Asabi’s stock 'Modern High Gain' distortion module with the legendary sound of the ProCo Rat - with its arena rock rhythm tones and soaring leads!

A Rat On Steroids!

Large Mouse delivers all the snarl and spit of the original and celebrated Rat, but with many more features and control. Coupled with an active EQ, 4 clipping options and Jackson Audio’s innovative 'Gain Cycle' feature - you've never heard or seen a Rat like this before! To make the Large Mouse even more faithful to the original tone, Jackson Audio procured the mythical LM308 chip that is used in the most sought-after vintage units.

Easy to Install

Dead simple to install, you simply unscrew the Asabi’s backplate, remove the stock distortion module and replace it with the Large Mouse. Voila! Your new distortion mode with all its features is accessible, ready to be the most raucous rodent on your board - ever!
