The only ones that comes to mind is Atomic Amplifire and Two Notes do power amp models. Any others? I find it interesting that putting things in the fx loop or going into the fx return is a common practice in the real world, yet not so much in the modeling world. I used to go in through the return of my amp using different preamps all the time, back in the day. It would be cool to be able to do this with my Helix!
