From the post
This is a great sounding Orange amp emulator by EQD. The EQ controls allow you to boost those frequencies instead of just rolling them off. Lots of big burly Orange tone in this FET based circuit. I've laid it out so you can board-mount all 4 pots from the solder-side of the board using right angle PCB mount pots.
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.
