Wow, that delay is just incredible! I remember back when someone first put out the idea for this project and people started crawling all over it wanting to make their own (me as well, though I never got around to it!)
This just blew away all my expectations for what the first one would look like, congrats! So, yours is configured with a uC switching system for the buttons that interfaces with some solid state switching chips to route the PT2399s?
By the way, any info on those LED covers? They look spectacular.

That's awesomeness right there. Inspirational work Chris. 
great design! i've been thinking about that idea for a while now, just haven't gotten it together... are you using a crimping tool for the header pins/wires?
I
should, but i'm not. As of now I am fiddling with small pliers for crimping. I strip the wire, put the end of the wire cover in the first "C" part of the pin, crimp that C down a little to hold the wire down so it doesnt move, then really tightly squeeze the second "C" around the stripped wire end till I feel that it's never gonna go anywhere. Then I tighten the first "C" around the wire insulation to the same end, and finally dab a little solder at the wire tip for added security.
Excellent work, Chris!
Special kudos for getting this done in such a small box. Must have take very careful PCB design.
The next step is to make your effects "Nintendo cartridge"-style 
Or have several effect PCBs in an external box and connect them to the base unit using a ribbon cable, while switching between them with a nice relay system. Ok, I'm taking it a bit too far..
I thought about the "nintendo" style a bit, but I decided to just stick with this way. One problem is the potentiometers - you need different potentiometers for every effect, so they have to be switched out as well. Designing each effect around the potentiometers is a possibility, but it would be limiting and annoying. Integrating them into the effects units PCB mount solved that problem (and also allowed me to make those face plates interchangeable) but also complicates the exchange process a little, since you need to remove the pot nuts. You'd need a way to connect the PCB to the base unit cartidge style but stably enough to have the potentiometers poke out of the effect and not be sensitive to pressure on them.
The external box idea is limited to the cartridge style for the same reason - pots. Closest I will come to that is a large box where 5-6 of these modules fit in - sort of like some of the multi-effects pedal boards that people make every now and then.
