From the post
Here is a variation on the Rat theme. I wanted to do a MOSFET Rat since I have a few CA3240 dual op amps lying araound and I like the sound of MOSFET transistors of hard clippers. Caps is enlarged a bit for a bit more low end and a switch for a 10uF running in parallel with 2,2uf cap is added for a bit more gain and low end. Stock output FET buffer is replaced with the second half of the op amp.
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.
