Evans Hydraulic Blue 2 Ply Bass Drum Head

Evans Blue Hydraulic two-ply bass head features a thin film of oil between the plies that suppresses unwanted overtones. A classic sound, short in sustain. Tension it tight for a real thump or loose for a more slappy sound. 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 3 colors: glass, black and blue.
