From the post
Had a request for this one and ended up drawing it up in Eagle. Rick Holt (frequencycentral) over on DIYSB designed this chorus and this is the latest version. It differs from earlier version with 2 toggle switches: One changes the effect from chorus to more of a vibe, and the other changes the sound (Space/Warble). I've also uploaded this to OSHPark if anyone is want's a fabricated board of this one. Best fit will probably be in a 125B.
Schematic
This is a board layout, a drawing of where each part goes, and the post may link the schematic it was drawn from. Open the layout at Effects Layouts (blog). No KiCad fragment has been drawn for this circuit yet.

Check before you build · 2 values the reader of this layout was not sure of
- 3.3n cap right of the PT2399 top: a drill mark overlaps the second digit so it looks like 3.8n; schematic C14 is 3.3n
- the 16-pin IC is printed PT2399 on the board (the schematic only calls it IC2)
