This is a printed circuit board that allows you to build either the Jan Ray or Timmy overdrive, both of which are considered to be at the pinnacle of overdrive pedals. They are popular among DIY enthusiasts, and there are many build logs available. Although there are four knobs, the number of terminals on the volume pots to connect is small, so the number of lead wires to wire is not that many. The number of parts is also small, making it a good subject for beginners to try. Basically, all parts can be obtained from Akizuki Electronics Trading. How about making your own effects pedal? It can also be used for effects pedal making events. Please see the blog for instructions. https://oue.hatenablog.com/entry/2025/01/22/170728 The listing is for the PCB only.
