Its perfect for the modern, hard-driving thump+click sound, it's basically pre-eq-ed. Point and shoot, at least with a hole in the front head, just stick it in there, and move on.
Pre-eq-ed also means it may be difficult to NOT get the big thump+click, so if you're looking for a natural, jazzy, whatever sound, it won't be your favorite.
It absolutely kills on bass cabs. Good on floor toms. I keep meaning to try it on scream/yell vocals, and blended on a guitar cab. I have one now, I will buy another.
