Questions
What parts does the Schematic Fuzz 1509B use?
58 parts, built around the MPS2222A and MPSA13. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Schematic Fuzz 1509B KiCad files?
From the devilmollusk/fuzz_e_neuron repository on GitHub, at the commit this page was made from: the board is Schematic Fuzz_1509B.kicad_pcb and its schematic fuzz_e_neuron.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schematic Fuzz 1509B design in my own project?
Its repository states no licence, so its author keeps all rights: ask devilmollusk before reusing the design.
