i have both the e609silver and the e609black. the silver one is garbage. the black one gets alot of use for me. its smooth and gets alittle more low end than the 57 which is great for some amps(especially crappy amps, the black 609 seems to "forgive" them better than some mics). the 609 black is discontinued and i havent tried a 906 yet to compare the two. ii bet you can find a black 609 used though. good luck.
