I don't believe they are entirely built in China this time around. There are lots of options to customize what you want out of it. The boards are designed by Bryce/Epic Amplification, and his catalog of mods that he offers is available from the factory with these amps. Pretty sure Doug wires the populated boards in the chassis, or at least helps out with it.
I took delivery of one that has a 2 channel BE/HBE vibe, and looks like the Runt series. It's pretty much on par with my Friedman modded 20H that I've had for a number of years (where the mids sit is quite different; otherwise very similar sounding). I opted to not upgrade the OT, caps, or have a loop installed because I plan on doing those myself shortly. As-is, man it rips.
