Cosmonaut Colossus

Project overview

This fuzz delivers an Airy, open, and harmonically complex tone with a wide range of gain control.

Introduction

This pedal covers everything from soft overdriven tones to nasty fuzz sounds on its high gain settings, always delivering clarity and harmonical richness. This device can get even more versatile by rolling down the volume knob on your guitar!

Its simple yet straightforward Big-muff tone stack will fit all your needs to shape your sound and launch your creativity to the stratosphere.

To build this pedal properly is a must to use low gain NPN silicon transistors, such as the stock 2n3903 or 2n222a like the one I used to verify this build. The key is to choose transistors with a gain lower than 200hfe. Higher gain transistors might occasion unwanted noises and oscillations.
