While I use most all of my guitar amp emulators on a regular basis and, for the most part, find them adequate for my recording needs I've always wished that they could "push more air". I'm really hoping, though not in any way counting on, Amp4 stepping things up in this regard to a another level. But recently I had the time to just take an afternoon off and really A/B my different packages and study their assets and liabilities. And in doing so I popped up a program I've had for awhile now...even upgraded regularly...but really hadn't used; ReCabinet 4. Woah. What an (acknowledged) dimwit I've been. This thing is great. Looks like most of my amp sims will be "head only" for awhile. Highly recommended.
