From the post
Found this cool little thing at DIYSB. A fairly simple high gain circuit which is supposed to emulate a cranked Marshall using three MOSFETS with a J FET buffer up front. There is a simple treble roll of at the end of the circuit. Write-up, schematic and a demo 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 Dirtbox Layouts. No KiCad fragment has been drawn for this circuit yet.
