It measures 106.7 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
26 parts, built around the TL082. 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 MX994/ABAP-Pedal repository on GitHub, at the commit this page was made from: the board is ABAP.kicad_pcb and its schematic ABAP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask MX994 before reusing the design.
