Evans Hydraulic Glass Tompack - Fat Early Rock Tom Sound

In this review the Evans Hydraulic Glass Tompack is judged as a go-to choice for drummers chasing a fat, short rock tone with minimal overtones. Packaged as 10 in, 12 in and 16 in tom heads, these two-ply hydraulics sandwich a thin layer of oil to reduce sustain and sharpen attack, which makes them an instant fix for drums that ring too much or for younger players who want an effortless, vintage rock sound. The bottom line: if you want a punchy, low fundamental and easy tuning, this set delivers.

Key Features

• Hydraulic oil layer: A thin film of oil between the plies suppresses unwanted overtones and reduces sustain for a focused, vintage rock tone.
• Two-ply construction: Two plies provide extra durability so the heads stand up to heavier hitting and last longer in gigging situations.
• Early rock sound: Designed to deliver a fat, deep and short sound that sits well in classic rock and pared-down band mixes.
• Level 360 Technology: The Level 360 edge treatment makes seating and tuning the head easier, widening usable pitch range and improving consistency.
• Made in the USA: Designed and manufactured in the USA for consistent quality control and reliable manufacturing standards.

Who It's For

The Evans Hydraulic Glass Tompack is ideal for rock drummers and studio players who need a strong low-mid fundamental and quick decay, especially those playing 70s-style rock, garage or pop where a focused tom thump is preferred. Players with drums that are prone to excessive ringing will appreciate the instant control the oil layer provides, and teachers or younger players will like the forgiving tuning behavior.

Drummers seeking long sustain, modern resonant tones, or clear open tom ambience should look elsewhere, such as single-ply or coated heads designed for extended resonance and bright overtones.

Pros & Cons

Pros

• Consistently muffled rock tone with strong attack and low fundamental that sits well in band mixes.
• Durable two-ply construction handles aggressive playing and offers good value for frequent use.
• Easy to tune and stay in tune thanks to Level 360 Technology and the head's stable response.

Cons

• The intentionally short sustain and muted overtones limit ambient, open-sounding tom textures for genres that need long resonance.

Frequently Asked Questions

Do these heads reduce sustain?
Yes. The oil layer between the plies lowers sustain and suppresses overtones for a short, focused sound.

Are they durable for heavy playing?
Yes. Two-ply construction provides extra durability for aggressive playing and regular gig use.

Can I tune them high for more attack?
Yes. Tensioning them tighter increases attack and thump, while looser tuning produces a slappier tone.
