The Torus Lo-Fi Fuzz is a pedal that aims to replicate the gritty, low-budget garage tones of an overloaded cassette recorder. It is based on the Mid-Fi Demo Tape Fuzz, which was designed to recreate the distortion created when running a guitar into a cassette recorder and cranking the gain.

The circuit of the Torus Lo-Fi Fuzz consists of two main building blocks. The first is an op-amp gain stage, similar to a Distortion+ circuit. The low-pass frequency of this stage changes with the gain, unlike most drive circuits where the potentiometer controls the feedback resistor and keeps the low-pass frequency constant.

The second building block is a basic Baxandall tone section, which allows adjustment of the treble and bass frequencies. This gives the user some control over the overall tone of the fuzz.

What makes the Torus Lo-Fi Fuzz interesting is that, like a cassette recorder, it does not use clipping diodes to generate the distortion/fuzz sound. Instead, all of the distortion is generated “unintentionally” by op-amp clipping. This gives the pedal a unique and rough-around-the-edges character.

The Torus Lo-Fi Fuzz is a direct clone of the Demo Tape Fuzz, with no modifications. It is a great project for beginners as it has a low parts count and is relatively simple to build.
