Ok, I started working on these two years ago but they're finally done. And WOW I love these! I first heard the Hudson broadcast on probably TPS several years ago and loved it. It's unusual for me to be wowed by a pedal demo and then want it.
I had initially built the first revision of the simulcast but it squealed. @Robert very graciously made a revision AND sent me one. What a guy! I stripped that first board and put all* the components on this one as detailed here. The newer revision is much much nicer to build and everything fits well without putting caps on the back of the board. Ultimately, I left the charge pump out on the simulcast because I want the fuzzier blown out end of things on this one, and I'll mostly use the duocast at 27v.
As for the duocast, it has been sitting populated on the back corner of my desk for over a year. I had been in a particularly foul mood one day while working on it and broke a trace on the voltage switch, which was easily fixed with a jumper. The duocast also has a green/red bi-color LED for the gain switching. Also shout-out to @Phil hodson and his troubleshooting thread early on thinking he borked his duocast build but really he didn't understand what the right footswitch was doing
Phil's come a long way in his skills 
No sockets are installed in either build; I soldered the GT402Bs directly to each board. I did audition some other transistors, but I removed the sockets before final assembly. At some point, maybe even last summer, @blackhatboojum supplied me with the 330uf caps I forgot i needed. Clinton is a solid dude.
It seems like folks around here either really like or really don't like the -cast builds. I'm absolutely in love with them.
These are the last pedals I plan on doing with Arnold Lobel's Frog and Toad on them. As with my Pot and Kettle build, I drew the art myself in inkscape from reference in the Lobel book. My daughter is really into Frog and Toad, and is excited to see them on my pedals. I had completely different designs for these initially, and even made some decals but ended up scraping them. The simulcast design had the gain switch improperly labeled. I had done a silver foil decal for the duocast but it didn't show well on a dark grey enclosure like I had hoped, and the foil itself didn't come out great. I'm much happier with the Frog and Toad theme.
Here are a couple pics of the old revisions I did for the decals
