Hey Gutbucket,
Love the thread you linked to--some great ideas. In another thread, Chris Church proposed the idea of split omnis, with a homemade baffle blocking the rear, sides, and top/bottom of each mic. The baffle would be covered by acoustic foam. I've bought/ordered supplies to create this but haven't tried yet.
Have you tried anything like this? What do you think? Any tips?
Thanks,
Brendan
