You're absolutely right to clarify! My apologies for the previous oversight. Let's get straight to the description of the Evans BD22EMAD drumhead.

The Evans BD22EMAD is a highly popular and versatile 22-inch Clear Bass Drum Head from Evans' renowned EMAD series. It's designed to give drummers ultimate control over their bass drum sound, balancing punch, power, and low-end thanks to its innovative Externally Mounted Adjustable Damping (EMAD) system.

Evans EMAD Series: Customizable Bass Drum Sound

The EMAD (Externally Mounted Adjustable Damping) series is a flagship line for bass drum batter heads, prized for its ability to quickly and easily modify the drum's sound without internal muffling. This makes it incredibly versatile for a wide array of musical genres and playing situations.

22-inch Diameter for Standard Bass Drums

The "22" in the model name indicates that this is a 22-inch diameter drumhead. This is the most common size for bass drums on standard drum kits, making the BD22EMAD a go-to choice for countless drummers.

Single-Ply, 10-mil Clear Film Construction

The BD22EMAD is constructed from a single ply of 10-mil (0.25mm) film.

• Single-Ply: Provides an open, vibrant, and resonant sound, allowing for good sustain and sensitivity.

• 10-mil Thickness: This is a medium-heavy single-ply thickness, offering a robust attack and excellent projection while maintaining responsiveness.

• Clear Finish: A clear drumhead emphasizes the attack and fundamental pitch of the drum, typically resulting in a brighter, more open, and resonant sound compared to coated heads.

Signature EMAD System: Externally Mounted Adjustable Damping

This is the core feature that sets the EMAD series apart. It consists of an externally mounted plastic sleeve that holds two interchangeable foam damping rings of different widths.

• Effortless Adjustment: Drummers can easily swap between the included foam rings (or remove them entirely) without taking the head off the drum or reaching inside. This allows for quick sound adjustments mid-gig or during recording sessions.

• Tailored Sound Control:

  • Thinner Foam Ring: Provides subtle dampening, allowing for a focused punch and controlled sustain while retaining some resonance.

  • Wider Foam Ring: Offers maximum low-end and attack by providing more aggressive dampening, resulting in a drier, more muted "thud" with minimal sustain.

  • No Ring: Allows the head to resonate more freely for a fuller, more open sound, similar to a traditional clear single-ply head, but with the added benefit of the EMAD sleeve's inherent subtle control.

• Versatility: This system makes the BD22EMAD extremely adaptable for various musical styles, from open rock sounds to tight, punchy metal or precise studio tones.

Level 360 Technology for Superior Fit and Tuning

All modern Evans drumheads, including the EMAD series, incorporate Level 360 Technology. This innovative collar design ensures:

• Perfect Fit: The drumhead sits evenly and completely on the drum's bearing edge, making it easier to install.

• Effortless Tuning: The improved contact allows the head to tune up more easily and consistently across its surface.

• Extended Pitch Range: Drummers can achieve a wider range of usable pitches from their bass drum.

• Optimized Sound: Ensures consistent head-to-shell contact for the best possible tone and resonance.

Sound Characteristics

The Evans BD22EMAD, with its clear film and adjustable EMAD system, typically produces a bass drum sound that is:

• Punchy and Powerful: Delivers a strong, impactful attack.

• Controlled and Focused: The EMAD rings effectively manage unwanted overtones and decay, providing a tight and articulate sound.

• Versatile: Its sound can range from relatively open and resonant to very tight and muted, depending on the chosen damping ring.

• Clear and Defined: The clear film emphasizes initial attack and clarity, while the damping system enhances definition.

Intended Use

As a bass drum batter head, the BD22EMAD is an excellent choice for:

• Rock and Metal: Provides the driving punch and controlled sustain essential for these genres.

• Gospel: Can deliver powerful, articulate bass drum sounds.

• Studio Recording: The adjustable dampening is incredibly valuable for dialing in precise sounds in a controlled environment.

• Live Performance: Offers strong projection and the flexibility to adapt to different venues and sound requirements.

• General Purpose: A true "workhorse" head that performs exceptionally well across nearly all music genres where a powerful and controllable bass drum sound is desired.
