From the post
Pedro (WTFiCanBuildMyOwnPedals) came up with this distortion/overdrive a while ago. It takes elements from both DOD250 and Boss DS1 but it has its own thing going on. A bit less gain than a DS1 and cap values in the signal path is adjusted. The hard clipping diodes are a LED and a silicon diode for assymetric clipping
This one is verified by Pedro.
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.
