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.

What it is, in one paragraph

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 layer is the defining feature: it acts as a near-instant damping mechanism, producing an ultra-wet, short-sustain tom voice that's the canonical 70s rock-tom production sound. Available in 6 to 18 inch diameters.

Verdict and the affiliate hook

If you want the 70s rock-tom sound, the wet, controlled, John-Bonham-era tom voice, the Evans Hydraulic Black is the canonical answer. The oil-filled damping layer delivers the sound out of the box; no moonbag-and-tape ritual required. For 80s controlled-rock tom voice, Pinstripe is the choice; for modern-rock open tom voice, G2 Coated is the choice; for the 70s wet sound, Hydraulic Black wins.
