The Craig Anderton Tube Sound Fuzz is a popular DIY project that has been modified and used for many years. It is based on a CMOS Hex inverter and can generate thick fuzz tones. The design was commercialized with the Way Huge Red Llama, with some minor changes to the original circuit. The effect can also produce more subtle overdrive tones when the gain pot is turned down. It can be used as a low gain overdrive or boost by adjusting the gain and volume knobs. The tone of the effect has a moderate mid-range cut and adds depth to the guitar signal. The controls on the TSF/Red Llama include a volume knob for adjusting the total output and a gain knob for controlling the fuzz. Overall, it is a great project for DIY enthusiasts to build.
