stereo micing an acoustic

[snapper]

I'm using a pair of sm81's to mic an acoustic guitar, positioning one 6 inches away pointed at the 12th tret and the other pointed at the sound hole. I know I should be checking for phase problems. Im runing the mics to a 1642 mackie mixers pre-amps and dont see a button to throw one out of phase. Can anyone tell me a way to do this or check for a phasig problem?

I am no expert, but if you had phasing problems, you would be getting a weak bland sound. If you need to change the phase and your mixer does not have a switch, you will either need to change your cable or get some outbound peice of hardware.

if the mics are relativly the same distance from the guitar then you should not be having too many problems with phase.
If the sound of one mic is more powerfull that from both however you are having some problems. You can solve this with the placement, no need for a button! (but sometimes it can defintly be a plus)

To check for Phase problems listen to it in mono.
If the sound is thinner-weaker-disappears-or sounds funny, then you most probably have a problem.

As James said mic placment should help slove the problem.

I guess I'm almost trying to create a phasing problem so I can easily identify it if it comes up. But as far as listening to it in mono how do I do this? pan to one side?

listening in mono depends on your monitoring setup. to listen in mono just make sure that one mic is not playing back (or being monitored) left and the other right. If you go through a mixer, just besure that both are panned center.
