Haha, I thought somebody might say that. So I fired up the Revalver Mk III demo for the first time in a couple of months, and I loaded in one of my beta impulses. At first I didn't like it, but then I realized that by default Revalver processes the impulses to add simulated speaker breakup, etc. - turn all those knobs down!
Then it sounds way more realistic. Finally the 6505+ model started to respond more like the real thing, and the XXX and JSX, and Peavey Classic models were awesome as well. I will say that they sound even better if you just use the preamp section, and not the power amp section, since the power amp is essentially predetermined with Recabinet. If you want the extra control over EQ that the poweramp section simulation normally gives you, just add some post EQ either between the preamp and the IR, or after everything.
I'm really not trying to push Recabinet at all when I say that it's legitamized Revalver Mk III for me. I was not expecting that to happen, as my initial experience with the Revalver Mk III demo a few months ago was very disappointing, and I tried all the same amp models.
