The circuit operates on a standard 9–12 V DC power supply and includes protection and signal conditioning stages to ensure reliable and clean performance.
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
41 parts, built around the RC4558D, 1N60P and NMJ4HCD2. 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 PanagiotisPrountzosCS/DistortionPedal repository on GitHub, at the commit this page was made from: the board is pcb/pcb.kicad_pcb and its schematic pcb/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
