I'm familiar with the B100R, love it, and am thinking about getting one. However, I'm also tempted to spend an extra bill to get the B200R instead. Can't decide which way to go. Some of the additional features of the 200 are attractive, but not crucial. For me, there are two crucial issues/questions: 1) Tone: The B100R has an incredibly tubey tone for a solid-state amp, and this is the sound I love and want. My question is, does the addition of a tube preamp to the B200R make it even, well, tubier? That is, is the tone more or less the same as the 100, or is it appreciably better (assuming you like that kind of tone, of course)? 2) Volume: Searching through the archives I discovered that there is some disagreement about whether the 100 is loud enough for a full rock band. Some people say hell yes, others say not quite (at least, with a heavy-handed drummer, an extra guitarist, etc.). So it seems that the 100 is right at the edge in terms of adequate volume, which makes me think that the 200 might be just louder enough to erase any doubt. On the other hand, at least one poster suggested that the 200 doesn't have any more "useable volume" than the 100. One would think that 220W would be noticeably louder than 100, all things being equal, but in this case is it? So, can we collect in one thread here the opinions of folks who have experience with both of these amps? If you were choosing between them, and wanted lots of warm fat tubey tone, which would you get? Thanks in advance.
