Evans Hydraulic Glass 13", TT13HG, Tom Batter

The two layers of the Hydraulic Head are separated by a thin film of oil. This produces a strong dampening of the vibrations and shortens the sustain. The play-feeling isn`t affected by this - the address of the Hydraulic Heads is very fast and direct.

EVANS Hydraulic Glass features: 2-ply (Outer: 0.18 mm, Inner: 0.17 mm) Oil film between the two skins creates strong dampening and short sustain
