You can move the mics around in thu/th3.
I guess just the differences in mic types showed the how far emulators are from the real thing. . A real ribbon sounds obviously different than a sm57. In th3/thu, it's almost hard to tell which is which.
All this is to say, I definitely started reamping after late night headphone sessions. I might record in thu, but I'm likely to use a real recording of my amp in the end. The real amp with real mics is just cool.
