Very good product! As a drummer, my style ranges from 70s Prog and Psych Rock to Indie and I bought this set for my first Drum Set (Yamaha Stage Custom with 12" and 14" and 18" Toms).
I remember that I was really satisfied with the sound they made right out of the box, they must be tuned a little bit lower, better frequences.
It does really improve your drum set sound but cuts a little bit on the sustain (because of the oil between layers). For me that's not really a problem.
Don't be scared if (with regular playing) they appear really used, its normal in these heads.
It does really fit the genres I play as I preffer a instant attack on the toms, and they do really punch quite hard, don't sound (at all) "muddy" if tunned right.
Evans is very good brand and this set is really easy to get in tune.
It does feel right, it sounds right!
