Evans 20" Hydraulic Tom Drum Head - Glass

Evans Hydraulic tom heads deliver the short, punchy character that defined rock drumming in the 1970s. The 20" size suits floor toms and mid–range rack configurations. Built in the USA, these batter heads employ a unique internal design—a thin oil layer sandwiched between two plies of film—that quells unwanted overtones whilst maintaining articulate attack and controlled sustain.

The construction uses 6.5 mil and 7.5 mil film plies, creating a durable two–ply assembly engineered for durability and consistency. Level 360 Technology facilitates easier tuning across the head's full pitch range, reducing the tuning labour often required with single–ply alternatives. The hydraulic damping produces a notably dark tonal character with minimal ring—a signature that remains distinctive in both studio and live settings, particularly where controlled sustain matters more than resonant bloom.

The glass finish delivers the same damping properties as Evans' other Hydraulic variants (red, blue, and black) whilst offering visual clarity that suits transparent or mirrored drum shells. Players working in rock, funk, and R&B contexts benefit most from the defined attack and short decay, especially in close–miked studio arrangements where head noise reduction improves isolation and editing efficiency.
