I've owned the v2 210 350w Combo and the v3 210 500w combo. I currently own the v3 210 cab. And have on a couple of occasions used one of the v1 combos.
The v1 combos, just don't waste your time. A forgettable tone and seriously underpowered but overweight.
The v2 combo. It was OK. I didn't know as much as I do now about getting a better sound out of an amp so perhaps a bit of knob twiddling might have helped. It was usable, a decent enough tone, but lacked a bit of something. It was also a bit heavy and cumbersome to move around. I didn't dislike it, but I didn't love it either.
The v3 combo is leagues ahead of the previous 2 in my opinion. Tones, volume, portability, usability. It's a really great sounding combo. I sold mine, but I've got a mate who's got one and if we share a lineup and he's letting people use the v3 I'll use that.
The v3 210 cab is just excellent value. Light and sounds good.
