?Before you jump face first into using a bunch of microphones on one guitar cabinet, you may need to make sure you understand a few fundamentals of recording mega huge metal guitar tones (or any other style for that matter)

Keep in mind that this 2 mics on a cabinet thing is a trick. A pro engineer with an enormous understanding of phase, microphones, preamps, etc decided to mic the back of an open back cabinet, took the hour to align the microphones perfectly, and ended up liking the tone.

If you are new to recording, DO NOT SKIP THE FUNDAMENTALS.

For example:

1) Based on your own experience, where is you favorite place to mic the speaker with a single mic?

2)Based on the tone you are going for, which mic do you like?

3)How many mics have you tried?

4)Based on your own experiences, do you like dynamics, condensers, or ribbons on guitar cabinets?

5)Are you better off knocking the highs down on your amp and using a SM57 or are you better off boosting the highs on your amp and using a ribbon mic?

6)Are you better off knocking the highs down on your amp with the 57 placed towards the center of the speaker or are you better off boosting the highs and moving the 57 toward the edge of the speaker?

7) Repeat step #7 with every mic you have.

How did these choices work in the mix when fighting with drums, bass, vocals, etc.?

You can see there are many possibilities when recording guitars. When you add a second mic to the deal (which CAN be a good thing) you have doubled your possibilities and added a new dimension (phase and comb filtering) to deal with. The way I see it, every time you add a new factor in your recordings, you are increasing your chances of screwing it up.
