so we have about 4 mics now, but are thinking of getting one of those drum mic sets. anyone have any thoughts or suggestions? also, we would like to stick to 4 mics if possible (4 track recording), and i would like to hear some input on where the best place to locate each mic would be. we have a simple 5 piece drum set. didn't Led Zepplin record their drums with a 4-mic setup?
