From the post
I'll give you heads up now. This is going to be Wampler Week. I laid out the Plexi-Drive a long while ago, but I wanted to give this "Marshall-in-a-box" circuit another go with board mounted pots and trimmers for those pesky J201 JFETs.
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.
