From the post
This is Madbean's version of the famous Univibe pedal.
I've added a "Multi-Vibe Mod" to it.
You can find all infos on this circuit or buy one of his PCBs here:

09/11/2016 Layout Updated! Changed the charge pump daughter board.
There's also a different but verified layout by Savvas in the Forum section.
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 Tagboard Effects. 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
- Transistor types are edge labels matched to columns/rows by position: 12 x 5088, one 5089 (top, right of the J201), one 5087 (centre, in the column above the bottom '5087' label)
- 250K trimmer has no name on it; the red 'Offset' label at the top edge is assumed to refer to it
