Ok, I did some searches but didn't end up with a whole lot of information here. I'm looking for a microphone around the $100-ish range that will handle a real bass-heavy tone without crapping out at medium / medium-high volume. I keep hearing good things about the Shure SM-57 (I think that's the right model, or maybe it was the 58). From Shure's website, it looks like the thing begins to roll off around 100 Hz and is -10dB at 40 Hz. Is there anything in this price range that has a flatter response? Any other suggestions?
