There is a point where the hole is so big that it won't even matter. There was a site where they talked about this and other drum information. I found it very helpful.mute":386co6os said:how big of a porthole is too big?
when i was recording a while ago, the engineer cut a porthole for the mic, but just used scissors. now, the whole has just torn into a big ragged mess. i'd kind of like to make a clean hole, but it would be pretty big. probably 6 inches in diameter. is it even worth it to keep the head?
