From the post
This one has been requested for some time but since there was no confirmed schematic avaiable I didn't want to pull the trigger. But Aion Fx just uploaded a schematic with their Termina project. It also includes a trimpot which affect the bass response and clipping. Schematic and more info is avaiable HERE.

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.
