I'm a big fan of the Barbershop - hope this one lives up to it.

I made a point to point layout for the barbershop if anyone is vaguely interested https://vero-p2p.blogspot.com/2020/07/f ... p-p2p.html

I'de love to find out what's going on with the accountant too if anyone knows... :D

Yeah, not sure. Maybe they've forgotten about it? Could just buy the PCB and trace it I guess.

Legend - thank you so much. 🙂 whipped up a vero layout.

There's also a small / neater layout on guitar FX layouts in the unverified section done by someone else.

note: first vero posted had an error. I missed the jumper from pin 1 to 6 - doh... :oops:
