Historical Context and Positioning in the Range
As a true signature of Evans, the Hydraulic series fits into the sonic aesthetic of the 1970s: a dense, controlled sound ready for both stage and studio. Its "oil bath" principle makes it a unique option in the range, designed for drummers who want clear sustain control while maintaining a natural playing feel.
Who This Drum/Instrument Is For
This head is aimed at beginner to advanced drummers seeking an easy-to-manage sound with fewer overtones and straightforward setup. It is particularly suitable for Rock and Fusion styles, and more broadly for any situation where a clean impact without overwhelming resonance is desired.
Features and Innovations
The two-ply construction combined with the oil layer acts as an integrated dampener: sustain is reduced, attack is enhanced, and the sound remains consistent even at high volumes. Unlike added dampening solutions (rings, gels), the control is constant and does not artificially alter playing behavior.
Sound
The Hydraulic delivers a fat, compact, and highly controlled tone. The oil between the two films limits unwanted vibrations, resulting in a short and dry resonance and an attack that "cracks" effortlessly. The result is a focused sound, easy to place in a mix, with a distinctly "vintage" aesthetic, particularly effective in live settings and close-miking recording.

This drumhead is designed for a 13-inch tom. Its 13" diameter must match that of the drum shell concerned.
What sound does a blue Hydraulic drumhead produce?
The oil bath placed between the two plies provides a fat sound with a short, dry resonance. The attack remains clear and unwanted vibrations are minimized.
What is the thickness of the Evans Hydraulic 13-inch drumhead?
The construction consists of two plies of 7 mil each, an outer film and an inner film. This setup helps control sustain and holds up well at high volumes. The transparent finish is blue in color.
Is this tomhead suitable for rock?
This model is recommended for Rock and Fusion styles. Its reduced sustain makes it easier to achieve a focused impact, especially on stage or in close-miking situations.
Is it necessary to add gels or dampening rings?
The oil integrated between the two films already ensures a consistent attenuation of overtones.
