Looks pretty straight-forward according to the second vid.
Just wished they used something other than a Strat/Fender combo for it though. Still, I thought it did do a very good job of copying the tone. I kept thinking the real amp had a tiny bit more definition, but you'd probably have to be standing next to the thing to know for sure.
I don't know, there always seems to be this tiny bit of "deadness" sims have. This newer system seems to be light years ahead of the current crop of sims, but I thought I heard just a tiny bit of that "deadness" here to. The notes just seem to be ever so "rounded" off sounding, like they just don't have the same edge they get when played through an actual tube amp.
Did they have to make it look like a piece of futuristic medical equipment?
