doesn't work with fast metal, especially death or black metal, though....if you try to duck the bass under the kick while it's playing straight 16th notes, you could as well turn the bass off
i dunno man...even on pretty fast shit, i find it still helps to set up a sidechain comp. on the bass, but get it so that it's only hitting 2-3db of gain reduction with a quick attack and release. a little bit definitely goes a long way on that one.
