Evans 22 Hydraulic Bass Head Blue

Exclusive to the Evans line, Hydraulic heads have a layer of oil between the two plies to give you the fat, wet sound that was so popular in the ’70s. The oil acts as a natural muffler to decrease sustain and increase attack without affecting the feel of the head, as internal and external mufflers often do. Hydraulics have a solid attack and a controlled, quick sustain, and are best suited for rock. They are available in glass, black, and blue, and can be used both live and in studio.
