Project overview

This fuzz machine inspired by DOD´s Carcosa Fuzz produces a plethora of vintage and modern silicon waves able to shake you and your audience to the core of your bones.

Introduction

The Carcass Fuzz and the pedal in which is inspired, have their roots on silicon transistor-based fuzz pedals from the 70s, especially the circuitry of the Maestro FZ-1S. But make no mistake; our board is much more than a typical standard two- or three-knob vintage fuzzbox.

Two modes toggle adapt the pedal to practically any amp and player. The first one allows you a more traditionalist approach: Pair with an already dirty amp and experience smooth classic-rock leads and overdriven chord crunch to all-out fuzz mayhem waves that will get you shaken to the bones. The second mode is designed for a high-headroom clean amp, enhancing low-mid punch and adding complex harmonics for a fuller voice even when natural amp clipping isn’t present. Pair this one with a dirty amp at your own risk!

Before (gain) and After (bias) controls provide an impressive range of fuzz tones. But, before you get overwhelmed, you can start with both controls in the middle for a traditional fuzz tone, then raise the gain and peel back the bias and watch your notes melt into a puddle before you.

With tons of output, the Carcass can be used as a clean or crunchy boost before you begin getting into the domain of fuzz. The pedal has a natural voicing strong in presence to cut through a band mix, with plenty more available in that area by turning the Hi-Cut knob clockwise.

These are some of the several features this pedal offers, but there are many more to discover. And this is where you enter the scene.
