Used live , mic'd up , small hole in front head , small towel and weight on both heads.
14 inch deep drum
I like the wet punch and low end you get from this head , really nice lows out of a 20 incher ,
does need an impact patch if using hard plastic or wood beaters to stop wear . and this does take some of the click away in the attack.
lasts a long time , and very dependable.
