Black Cat OD / Freddy fuzz vero layout

[Xavier]

I hope everything is correct , please let me know if there's any error and I will correct it. I've been always curious about this one. Can I use any other IC? I haven't got any OP275 available.

Isn't it great this layout software?

You need trace cuts under R9, C4, C6, C8.

Vol1 and Vol3 connections also need reversing.
Vol 1 lug at output is always "ground"
Vol 3 lug is output from circuit
Vol 2 lug is connection to switch/output jack 

Otherwise, nice little layout
