Research + Designed the Schematic

I started this project by researching how existing bass fuzz circuits work. I found many great resources, and all of them seem to use a fairly simple circuit. I plan to use this basic circuit with some modifications to make it more useful for me. Also, from what I see, not many are using an actual PCB; most just use a perfboard. I want mine to be clean, so I'll be using a PCB.

I then designed the basic fuzz schematic for my pedal. This is currently using a fairly common fuzz circuit, but I plan to add some more features, like a gain knob and some more options for different diodes, which will give it a different sound. It has a TRS jack on each end, with the R and S pins grounded and the T pin as the signal, which lets the guitar cable plug into the pedal.
