What would be the best way to position a microphone record drums with one microphone?
Though seemingly a ridiculous question, as one whos strapped for cash and doesn't want to use a drum machine, how would you do this?
The short & realistic, if somewhat cynical, answer would be...
Do it like they did in the 50's - find a good-sounding room, keep moving the mic around the room until you get the best sound.
Without knowing the room [with one mic, the room is far more important than the mic], no-one's going to get a better answer.
