I commented on it
here, but I wasn't very detailed, so I'll go into specifics with your questions.
The VR I played had no punch and was very muddy in the low end while having a thin overall sound. It also did not have near the volume I expect out of an SVT. There was no feeling of 'horses under the hood' like you get with an SVT. On the in store demo, the amp would get loud, but it was very distorted and weak sounding. I thought halfway about tweaking the bias to see if it would improve, but thought better of it. The amp was also a good bit lighter than it should have been. AFAIK it's still at GC Nashville if any other Nashville TB'ers want to give a second opinion.
...to put it mildly
No, but they did move the bias controls to the back.
