I don't know how, but I totally missed this thread. Normally with 3 larger ICs I would say PCB, but there isn't actually too much else going on in it. Let me see if I can estimate how small I can get it and I'll let you know.
I found this thread when looking at the most recent request for the Emma Discombobulator. As it happens, version 1 of the Emma Discomboblator looks like it's pretty much the MXR Envelope filter with all of the mods in this schematic. But since the schematic that's floating around for that one is missing a lot of information I figured I'd try a vero layout for the MXR Envelope.
I've tried doing a layout for both the stock and modded version. But my layout for the modded version looks way too awkward right now. But here's the stock one anyway! It could probably use a second pair of eyes though .
