84 parts, built around the TL072. 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.
From the cdelmoral/tyrian-distortion repository on GitHub, at the commit this page was made from: the board is tyrian-distortion.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask cdelmoral before reusing the design.
