diogo--
glad i could be of some help. ;-) as for the V67 and B1 on vocals, there's just no comparison. the B1 is a "marginal at best" vocal mic, and the V67 is an exceptional vocal mic at that price point. of course, the V67, IMO, pretty much *sucks* as an acoustic guitar mic. they're totally different sounding mics.
keep in mind (and as is well documented around here) there's something "hashy" going on in the midrange of the V67 which, when compared to higher-end mics makes it a little "less than stellar" when you solo the track on its own, but it *is* a very good vocal mic for the $100, and i've never had a problem with it in the context of a mix. especially on voices that are a little thin/nasally. i prefer
my dragonfly for vocals, but that's apples and oranges. not to mention, the folks that come to me to record seem to be really turned on by the gold grille.....some even request "that gold mic" when they come in. it really seems to raise the bar on their game--go fig. and i'm not about to tell em that it's a $100 mic.
FWIW, my favorite use for my V67 is as a drum overhead--that "weird" midrange seems to help it bring out the woodiness in the drums. i keep meaning to pick up a second.....
sorry, but it seems we've turned your $100 expenditure into about $450....
cheers,
wade
