Each mic will pick up a bit of vocals/guitar, it happens.

EG recording stuff live, you have a 12" monitor in front of a guy who's standing at a mic stand, singing quietly (=high volume on mic) and playing acoustic guitar...
Although so long as you don't get feedback issues it can lead to some damn good guitar sounds.

And yes, you can record 2 tracks at once.

Thanks for your help. Would this make a significant difference though, if I wanted to perhaps alter the pitch of the singing (the odd notes) or add reverb to just one part?

If the singing is quiet and you need to keep the mic volume up, it gets worse. If the singing is loud enough and you can turn it down, you get less guitar (just don't scream it out).
It depends on how sensitive the mic is to off-axis noise (sound that doesn't come from directly in front of the mic where the singer is).

What it really depends on, is if you make the changes to the odd note and can't hear the difference, that's when you know it's fine.

If you can hear the difference, you could consider recording in parts: record the guitar, play it back via a pair of headphones (usually with only one cup on your ear) and record the vocals. Then you put 2 + 2 together and get what hopefully is 4.

Yeah, I was thinking of recording them separately, but I was wondering if I could make the best use of both the mics that I (might) have. I suppose two separate recordings will give me the best result. Thanks for your help :D
