Questions
How big is the Guitar interface PCB?
It measures 30 × 100.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Guitar interface use?
62 parts, built around the TL072 and TL431D. 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 Guitar interface KiCad files?
From the DomenLemut/AudioInterface repository on GitHub, at the commit this page was made from: the board is KiCad/guitar-interface/guitar-interface.kicad_pcb and its schematic KiCad/DI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Guitar interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask DomenLemut before reusing the design.
