Evans Hydraulic Black review: the 70s Bonham wet-sound tom batter
An editorial review of the Evans Hydraulic Black drumhead. Double-ply with oil-filled damping layer, ultra-wet short-sustain tom voicing, the canonical 70s rock-tom sound recreated on a modern double-ply head.
Reviewed by the Change Your Strings editorial team ·
The Evans Hydraulic Black is a double-ply 7+7 mil tom batter with a thin oil layer sealed between the two plies. The oil is the defining feature: it produces an ultra-wet, short-sustain tom voice that's the canonical 70s rock-tom production sound. Available in 6 to 18 inch diameters. Pick it for 70s rock recreations + sessions where the producer wants the John-Bonham-era wet tom sound; for modern rock with more attack, Coated Pinstripe or Evans G2 are better choices.
