mic placement with these

[terrible_buddhi]

Have a B1, B3, 2-SM58, and 4 - Sennheiser e604. I have a mackie 1604vlz pro, and presonus firestation with 2 tube mic preamps built in....thoughts on mic placement?

You'll be a bit limited when it comes to mic'ing your kick drum
but you're okay otherwise.
I have a friend that uses an SM58 to mic his kick and he likes it, but it wouldn't be my first choice. You may have to use your B1 on kick, backed off a bit with a pop screen to protect it. The B3 would seem like a better choice because it has the pad, but it is also the only mic you have that would be suitable as an overhead (in omni pattern).
You have the e604's which are great for close mic'ing of snares and toms (you may or may not need them all depending upon how friendly your room is) The SM58's are also good for close mic'ing drums, but you may want to use one of them on the batter side of your kick to punch up the attack.

Here's my suggestion:

B3 overhead, just above and in front of your head (centered over kit) set in omni pattern (pointed down of course). The B1 about 18"-24" from the resonator head of your kick in line with the sound hole (if there is one) a pop screen to protect it from pressure bursts from the kick drum. An SM58 pointed at the batter of the kick and pointed away from the snare wires or with a barrier (insulation). On snare, either one of your e604's or an SM58 (your choice). That may do it.If you need to bring up the sound of any of your other toms, you still have some mics to add on.
Save up to buy a good kick mic ($120-$180 should do it) and consider getting some small diaphram condensers for overheads. I use ecm8000's. They're not the best, but they work just fine and they're only $70 a pair at Guitar Center. (you will want a pair)
