I've had my Rumble 200 for some time now, and really love it. It tends towards a darker, more vintage tone.. but paired with the 1x15 I love it. So classic.
The overdrive is not my taste... just a bit fizzy and without much body or character... if overdrive is your thing then you'll probably be using pedals anyway, but can't recommend the Rumble for its overdrive alone. Also the "Contour" and "Vintage" modes aren't so useful I don't find. Contour seems to cut too big a chunk out of the midrange making it too bassy and too trebly, and Vintage seems to extend too deep and really lives up to the "Rumble" name. But that could all be personal taste.
All in all, very happy. If you want a good solid reliable amp with a clean, dark, vintage personality baked in, this is it.
