re Clint...
Overstated my prejudice, because like you said, we are on the cusp of doing a credible mic'd amp with several softwares out there already. Even the ancient POD Farm can compete beautifully. Amplitube, S-Gear, Guitar Rig (with a bit if intense love), HeadCase. Peavey Revalver 4 is dynamite.AmpLion, Kuassa (guardedly...)
So many others that sit like a real thing in a mix if you got enough floor ambience to mask the flaws of an isolated presentation. You can even set some of these to an extrapolated state of better than live in some ways.
My complaint is when they come in with a Marshal, Orange stack, whatever. Almost always an eq setting imposed on a digital square wave. Nothing ultimately Orange or Marshal about it except for the price.
Way more respect, and lend credibility to the guys out there who tell you up front, here's a fuzz box you can tweak around to get a good sound. Call it what you want and save the settings, but it ain't chasing some brand name.
Okay, off my soap box for now.
