I love this thread! Always great to see everyone's creativity!
I've gone through a couple of versions as I figure out more stuff I can do with the thing. I always enjoy building my own. Here's the first that I built for it. Ignore the dust. This one was designed for 2x in, 1x out and an amp switch.
Then as I realized I didn't actually do as much of the extra stuff and learned more flexibility with the HX Effects, I tapered down. I also modified my buffer to be a passive Y pedal so I could run an always on tuner. Just a preference of mine.
