Nyquist Aliaser with Envelope follower

[pinksoir]

Hey.

I'd love to build this stomp box: http://www.moosapotamus.net/IDEAS/nyquist/NyquistENV2.gif
Does anyone have a vero or perf layout for it (I can't really translate schematics...)?

I've found a PCB layout for it, but I'm not sure if it's entirely right. The layout is on this page: http://www.diystompboxes.com/smfforum/index.php?topic=72366.0

Also, I'd be looking to put a switch in to toggle the envelope follower on and off.
I don't think I'd ever use the CV input so I'd probably leave that out.

Erm... can't think of anything else but I have a feeling there was something...

Anyway, I really hope you can help.

Cheers.
