danno858 I think you definitely want different types of mics for different distances and directions. This was more about mic'ing close to the case, rather than at audience position.
And I really don't know the black art of proper mic'ing to sound like a live performance, but rather, in relative terms, putting mics in a spot that sounds the sweetest to your ears, may result in a better sounding recording than if your mics were placed in a different spot 6-24" away. TBH, I have a hard enough time telling whether one position is even better than another. They really just sound "different" to me.
