I played at the Fox Theater in Boulder the other night, and there was an SVT backline with a big Ampeg 8x10. I had my F1/AE410 rig with me, but decided to use the backline since we were the opening band and the headliner's bass player was using it. This was the first time I have played a gig with that quintessential rock rig, at least that I can remember.
I expected not to like it, but I did. It was set up to play clean, and I was impressed with how warm and clear it sounded. I did find myself adding a touch of midrange from the onboard preamp of my Stingray5, which I never do, but other than that it worked out fine. I did not miss the tweeter at all.
Surprisingly, though, for an 810 rig probably weighing in at 300 pounds total, it wasn't very loud. I had it pretty much pegged, and still used quite a bit of bass volume in my monitor. I was standing about 12 feet in front of the amp - far more than normal for me, but still.
+1 I've had the same experience. The good news is, set up to play clean, an SVT rig can sound very nice... fat, warm. However, the bad news is, when not pushed into the classic SVT grind, it's a 300 watt amp, and is not particularly loud or forceful, especially when driving that relatively low SPL fridge.
Makes you realize how much improved bass amplification is, given the size and weight of that old hog! Still nice if you want to grunt and grind, but a total waste of weight and space for a clean tone compared to what is out now IMO and IME.
