Questions

How big is the Delay reverb PCB?

It measures 100 × 42 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Delay reverb use?

46 parts, built around the PT2399 and 1N5819WS. 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 Delay reverb KiCad files?

From the adeboni/electronics repository on GitHub, at the commit this page was made from: the board is reverb_pedal/delay_reverb.kicad_pcb and its schematic alien_screamer/alien_screamer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Delay reverb design in my own project?

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