Wow, Bean! Those top three are *rammed*! But do you honestly need *six* trims in a single pedal? That sounds like an adjustment nightmare and a lot of support queries!
<looks closely>
Ok, so there's two MN3005's, so that's probably a bias trim and a coutput balance trim for each one, and that's four already...Ok, I think I see where you're going with this!

Anyway, damn well done for getting it all in there so neatly. Lovely work.
Also I think I need to get into your PCB-as-front-panels thing. They look great.
