I think Soft Tube Vintage Amp Room sounds fine. I've tweaked with it a bit and I'm happy with the overall results.. I don't agree with the negative reviews because I also have to tweak with my 62 deluxe and 66 reverberocket to get the results I'm looking for as well.... I've used several amp simulators over the years and so far soft tube is my favorite. I'm not saying it's time to sell your vintage amp collection but I will say soft tube is a nice tool to have.
I can see where in straight up plug-n-play it's not stellar but when I treat it like my other mic'd up tracks it's very workable- LA-610_SVAP_STA800 then a touch on room from OWS. The OWS plugin definitely adds to the realism of the sound. the 800 gives it some bottom and running the 610 input hot adds a touch of saturation to the sound.
All three amps in this configuration work well for me and that's basically what I do with real amp tracks. I really like the fact the amps are in a three-up configuration that you can switch between easily to compare.
I'd give it 5 stars if it had a decent mic selection.
Added mention for having to turn the bass down on the Fender when cranked- just like the real thing.
