…you need:

1 Demon Childe Guitarist
1 Demon Guitar, Pedal and Rig
Lashings of ROCK
Killer Riffs (to taste)
2 * condenser mics
2 * SM57s

Place guitar rig in the middle of the room. Position so the back of the amp is 3 feet from the back wall with the speakers facing the room.


‘Close’ Micing using the SM-57s
SM57 are flat and beefy. Using these as ‘close mics’ will give a punchy mid/low sound. 
Place the first SM-57 pointing at the left wall of the speaker. Put this mic 3 inches away from the speaker’s grill.
Place the second SM-57 pointing straight at the speaker’s cone. Put this mic 10inches away from the speaker’s grill. (you may have to slightly turn up the gain on this mic.
IMPORTANT: place a sound baffle between the 2 mics. A small pillow will do perfectly. This will cancel out much “common audio” between these 2 mics and thus increase the stereo image and decrease any phasing.

‘Far’ Micing using the Condenser Mics.
Condenser mics are bright, shiny and well defined. Using these as ‘far mics’ will give a clear, wide open spatial sound with a lot of definition.
Place each condenser mic in the corners of the room facing the amp. These 2 mics should form a triangle with the amp – with the amp being at the apex.
If you can, put a divider/sound bat (6 feet high, 4 feet wide, 2inches thick) 5 feet in front of the speaker. Position it so it’s thin edge points at the speaker. Having a wall in the middle of the room will increase the stereo separation of the 2 condensers.

Turn to amp to 11 and ROCK OUT!
Record the 2 SM-57 as a stereo pair. Pan one mic hard left and the other hard right.
Record the 2 condensers as a stereo pair. Pan one mic hard left and the other hard right.

Mixing
Pan the SM-57 to 70% left and right.
Invert the positions of the 2 condensers mics – ie: Pan condenser mic that was on the left side to 100% right and vica versa.

This will give you a WALL OF ROCK with great stereo separation

HINT:
While recording this, wear one of your mother’s dresses and it will become a WALL OF FROCK

AWESOME HINT:
Run your synths through the same guitar rig to create UBER-OHM-SUPREME-SYNTH’O’DOOOOM!
