Re: How do you know you've made your drum(s) sound their best?
As for your question, how do you know? When you like the sound from a distance, which only a recorder can do for you. Because no one touches the drums like you do. It''s a big factor.
Placing a recorder about 15 feet away from your drums....when you listen back...that is the real ear opener. So many times.... I like it from the throne, but out where it counts, in the audience, it's not what I want.
The first time I did this, I ripped off what little muffling I used. Then I learned to tighten my resos up, a lot.
The best way to do art, is to dispense with good and bad...and just get on with it.
