This is the best thing I ever purchased!
Playing sort of prog rock / funk fusion kind of a thing and this is the drum head I've been looking for.
The sound is very well declared and has little to no overtones.
Super easy to tune, just crank it up for 1,75 - 2 turns each screw.
Also, bonus, the center kind of starts looking like leather rather than worn out, so it's extra cool looking :D
