Re: Cutting a hole in the bass drum...How big, etc...
Here are the inside mics for DW Drums
My opinion is that miking a open BassDrum or through holes gives not a very good sound. Or if so, there are two mics needed - one also for the batter head from behind. Best sound in my opinion - this fat sound - is achieved by taking the Sound from the closed fronthead.
Anyway: taking mic sound is only a general source for the definitive mixing on the board - there you can get every sound you want.
