Buy Cheap Evans Hydraulic Glass Fusion Tom Pack (10-12-14) 
Buy Low Price From Here Now Hydraulics feature two plies that sandwich a thin layer of oil and give the fat, deep, and short sound pioneered by early 70's rock and roll. The oil decreases sustain and enhances attack and low-end. Additionally, Hydraulics are famously easy to tune...making them a perfect fix for troublesome drums and younger players looking for instant sound.

"Good Heads If You Like Fat Tone and Short Sustain" 2010-01-30
By Aaron Faletto (Renton, WA)
These are some of the most interesting, different heads I've used. They appears to be clear at first glance, but actually they have several "bubbles" all over the surface. I must clarify, they are not actual bubbles that are raised at all; the surface is smooth as any drumhead. There are just some air pockets in the oil layer between the plies, which is intentional and is not a defect. Weird, but not a bad thing. The sound? Warm, with short sustain. Remo Diplomats these are most definitely not. Almost a "thick" sound, IMO. Very 70's arena rock. Though I like the sound, I found it was a bit hard to get a definite tuning pitch. On the upside, however, I found that I didn't need to use Moongels, O-Rings, or any other dampener on my toms. Another plus: they are tough as nails. I've beat the crap out of these heads and they still sound the same as day one. Jazzers should stay away, but for rock, blues, and bar band drummers, these heads are great.
