I play pop-rock music. Have used zildjian ZBT series cymbals before. I can compare Zildjian ZBT and Samatya as Opel and Ferary.
Hi hat clear, has nice high sound tone, good attack.
18? crash warm, has good sustain.
20? ride has a lot sustain, can be used as crash/ride especially then hitting near the edge. Should sound good for D&B in my Opinion. Those who need clear straight bell sound might not like it. Bell is quite small, there are a bit too much sustain after hitting it. Has warm sound on the edge and nice sustainable highs closer to the center.
Minus is the printed (brand name) paint quality. Sticks got black after first try. Some black spots appeared on the hi-hat. I think, it will not be possible to see the brand name on the cymbals after the first cleaning.
Cymbals bag included looks a bit cheap. Has no separation for cymbals.
All in all sound is great. Quality/durability (except printed letters and bag) looks good.
