From the post
Here is the Menatone Pig overdrive.
There are two layouts: one with trimpots to help bias the JFets (would start at 9V) and one with fixed resistors (probably need to test different values to bias the JFets properly).
I've also added a charge pump (it works at 18V).
You can find the original thread from FSB here.
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.
