Hey everybody, my name is Nick and I'm an aspiring drummer and recording engineer/producer. I'm going to be recording some drum tracks soon and I have been told that if mics are placed incorrectly then the frequencies will cancel each other out and effect the sound you are getting. What are the guidelines you guys follow as far as mic placement goes. The mics we will be using are a sm57 for the snare, beta52 for the kick, and two MXL 993 condensers for the over head. And another question: Generally is it better to close mic everything rather than using over heads?
