This microphone is good for mic'ing up kick drums, or anything bass'y and punchy.
Although, I can't say it's as good as a shure or AKG. T.bone mics are very good, but I feel this mic is just a little bit lacking. The bass is ok, but not quite as rich as other mics.
So I would suggest considering what sub you are using. There's no point spending tons of money on an expensive mic if your speakers aren't up to the job (and vice versa). Therefore if you haven't got the best sounding PA, you'll probably get away with using this mic.
It's cheap, and therefore always worth buying and trying. But not the best sound. Although saying that .. I haven't been able to overwhelm the mic yet. So that's good.
