King in Yellow - distortion based on Exar Super Fuzz sf-2 schematic by @VitaliiBobrov -> SF-2 tracing
Original pedal was created by Polish company Exar Electronix (Janusz Raczyk and Leszek Gruszka)

It was my favourite pedal in the past for both guitar and bass and it was even better after some mods - like germaniums as clipping diodes, changing opamp..

and what i promised - here is whole project with gerber files: King In Yellow Project on GitHub

PCB was tested and assembled and its working but I messed up with a dual FREQ pot pins - this can be fixed by correct wiring.

schematic and assembled pcb:
