Questions

How big is the Tremolo PCB?

It measures 54 × 57 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Tremolo use?

59 parts, built around the TL072, MMBT3904 and US1B. 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 Tremolo KiCad files?

From the PyrooL/tremolo repository on GitHub, at the commit this page was made from: the board is tremolo.kicad_pcb and its schematic distort.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Tremolo design in my own project?

Its repository states no licence, so its author keeps all rights: ask PyrooL before reusing the design.
