I play in a general/indie rock band that plays medium sized venues quite often. I'm looking into buying one of these Ampegs - V4B or B2R. The two amps I have to compete with are a 40W tube Traynor and a 50W tube Marshall (both turn up about 1/2 way). Our drummer isn't too loud. Would the 100W tube in the V4B be enough power? (Either of the heads would be played through a 2-10 and a 1-15.) Also, does anyone have any personal opinions on the V4B? I've seen good reviews on here of the B2R. And by the way, I'm talking about the new V4B's, not the vintage ones. Thanks alot.
