The Hydraulic Glass delivers that thick, punchy bass drum tone that defined the sound of early-'70s rock. Two plies of 7-mil film sandwich a thin layer of oil that dramatically shortens sustain and pushes the low end forward, giving you a deep, slamming kick with minimal overtones. The clear "glass" finish lets you see the oil layer at work, which looks pretty cool, too.

Hydraulic heads are famously easy to tune, making them a great option for players who want a great bass drum sound without spending a lot of time dialing it in. Level 360 collar technology provides even bearing-edge contact. If you play rock, blues, or gospel and want a fat, controlled kick with vintage character, this head nails it.
