From the post
Here is a layout for a very famous pedal.
There were some noise issues with the original buffered version.
I've added a true bypass version below.
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.

- Several resistors are drawn translucent over track cuts (100K x2, 10K, 1M, 220K, 1K, 22K) and are counted as parts
- 130R and 430K next to the CLR resistor at top left: printed clearly, unusual values
