I can't believe how long it's taking me to get my perfect drum sound in my room. I'm pretty much there, but phew, what an effort it turned out to be. It's been about a year and a half now. By comparison, the first time I miced a guitar cab, it took me like 5 minutes. Same with bass guitar. Keys go direct in. Acoustic guitar is pretty easy, 2 mics. Drums are very involved, and have no comparison with any other instrument IMO.
I didn't add tom mics until just recently.
They really bring out the thunder of the toms. It sounds a bit hollow without them. They provide the creamy center.
I'm very envious of Bo's kick sound in his last playing post with the WMP Pearls. Very nice, and he probably got that sound in like 5 minutes.
