Evans Hydraulic series features two plies of thin film offering maximum durability, a fat, deep and short sound pioneered by early 70's rock and roll. Hydraulics are famously easy to tune, making them a perfect fix for troublesome drums and players with little tuning experience. Available in glass, black, blue and red.
