Default Re: Cutting a hole in the bass drum...How big, methods etc...

O's make reinforcement rings and they have an adjustable cutter over the years I have come to the conclusion that a single hole of 7" in a 22" makes the front head resonant properties virtually non existent so at that point you may as well dampen the front head completely, using 2 smaller holes does not.

KICKPORT also has the same effect, you dont hear the reso head anymore as the weight and it's rubber construction cancel the head.

I cut 2 holes , 1 on the left and one on the right slightly above the other.
The one on the right is for the microphone and the other to let the air out.

I cut the righthand hole just slightly larger than the microphone ( sm52 or senn 902) 4" the one on the right an inch bigger.

Tuning is everything and I only have to use minimal dampening when I get it right ( most of the time)
