Posted this in the recording forum, but you guys might help as well :

ok i m micing a 4x12 cab with a sm57 micing the center of the cone, and read that a u87 at the edge of the cone is quiet good for taking low end as a second mic, but there is my question how far from the cab do i put the u87, in which direction, what type of capture do i choose ? ( cardio, omni...), cuz i ve put it at the same distance as the sm57 ( like 3 inchs from the grill ) and the capsule is saturating and the sound is reallllllly bad , the sm57 is perfect but the u87 is non good placed i think.
Please give me some advices thx

I've always done it with a 57 on the grill then a u87 (or any LDC) a few feet away from the amp. Usually by listening to see where the sound starts to really develop and capture it there. There's not a set exact distance, you find it by using your ears. I've found that with 12" speakers it is usually between 3 and 4 feet away.
