I have an AKg D112 on the kick, audix i5 on the snare, audix D2s on the rack toms and a D4 for the floor tom. I want to add a single overhead to fill out the sound. What single mic would you use overhead? Trying to stay under $100, used is fine. I was looking at the Audix F15, Shure. PG81. Any other suggestions?
