So, I've got this gig, and I have a drum set. All the shows I've seen has a hole in there bass drum (I've been told it is called a wintle) with a microphone in front of the hole. I was wondering what the purpose of this hole was, what the hole actually did to the sound, is it necessary, and if it is necessary do I just cut out a hole or if there a specific size it needs to be? Lots of questions

It means when the bass drum is mic'ed up the sound produced is a lot cleaner. and the hole is usually always the bottom of the bass drum, off to one side.

As far as I've seen anyways
"Punk is a state of mind, and no one can take that away from you."

Its for miking the drum.

Usually the bass drum isn't loud enough without it being miked at gigs, and using the hole keeps a good natural drum sound, not a crappy "dudnt" sound.

But it isn't worth wrecking a skin by cutting a hole in it.
I wouldn't worry. My drummer has a £4,000 kit and his has no hole for playing live. Sounds fine
