Evans Tompack Hydraulic Glass Fusion Sizes 10,12,14" ETP-HYDGL-F
Hydraulics feature two plies that sandwich a thin layer of oil and give the fat, deep, and short sound pioneered by early 70's rock and roll. The oil decreases sustain and enhances attack and low-end. Additionally, Hydraulics are famously easy to tune, making them a perfect fix for troublesome drums and younger players looking for instant sound.
