This one should be rather simple to trace. There is a photo of the board on -> Reddit <- and the only thing that might be changed are the cap values as they are not identifiable from photos in SMD packages.
The similarities between these two are uncanny. It's almost like the exec fuzz was copied 1:1, then the attack swapped for R6, R5 made smaller with a pot in series for "variable voltage", and power filtering/pulldown added. I would have gotten the PCB fab to also assemble the transistors and diodes, but that's just me. I don't need no mojo!
FWIW I still support anyone who is trying to make a business from pedals, it's a thankless job and designing new stuff is hard. Sometimes it's better to focus on marketing and delivering a good product.
I love that Mythos is not only ripping off the same circuits I am, but they're getting their PCBs made at JLC PCB just like me too. I feel like such a pro when I see one of their gutshots.
