Evans GMAD 18 Inch Clear Bass Drum Head Review: The Ultimate Single-Ply Punch for Modern Drummers
If you have ever sat behind a compact kit or a bop-style setup, you know the struggle of the 18-inch bass drum. While these smaller kicks are incredible for portability and “tucked-in” jazz tones, they often lack the “oomph” and authority required for contemporary rock, funk, or gospel settings. For years, I found myself stuffing pillows into my small kick or cranking the tension until it sounded like a floor tom just to get some definition. The problem is that standard single-ply heads often feel too thin and “papery” on an 18-inch drum, while double-ply heads can choke the resonance of a smaller shell entirely.
Failing to solve this sonic gap leads to a kit that sounds unbalanced—your snare and toms might bark, but your kick drum just “clicks.” This is where the Evans GMAD 18 Inch Clear Bass Drum Head enters the conversation. It promises the best of both worlds: the responsive feel of a single-ply head with the durability and low-end punch usually reserved for much heavier configurations. In my quest for a “big” sound from a small drum, I’ve found that the right head isn’t just an accessory; it’s the primary engine of your kit’s groove.

What to Consider Before Buying a Bass Drum Head
A Bass Drum Drumhead is more than just a piece of plastic; it’s a key solution for defining the identity of your entire drum set. The batter head is the most significant factor in determining the attack, sustain, and fundamental pitch of your bass drum. Without a high-quality head that matches your playing style, even the most expensive boutique maple shells will sound lackluster. Choosing the right head allows you to manipulate how the drum “speaks” in a room and how it interacts with a microphone in a recording environment.
The ideal customer for this type of product is a versatile drummer who plays across multiple genres and needs a head that can adapt. If you are a heavy hitter who loves the rebound of a single ply but finds 10-mil heads too fragile, the GMAD (Grand Mouth Adjustable Damping) series is specifically tailored for you. Conversely, it might not be suitable for those who want an extremely wide-open, “ringing” vintage jazz tone with zero muffling, as the EMAD system is designed to focus the sound. Those purists might prefer a thin, uncoated calf-style head instead.
Before investing, consider these crucial points in detail:
- Dimensions & Space: It is vital to ensure you are buying the correct diameter. An 18-inch head is specifically for bop kits or converted floor toms. You should also check the latest price and availability to ensure you’re getting a genuine USA-manufactured Evans product.
- Capacity/Performance (Film Thickness): The thickness of the film, measured in “mils” (thousandths of an inch), determines durability and tone. A standard head is 10mil; the GMAD uses a 12mil film, providing 20% more thickness for increased low-end and longevity without the muffled feel of a two-ply head.
- Materials & Damping Systems: Look for heads that offer adjustable damping. Systems like the EMAD/GMAD allow you to change the focus of your attack without using internal pillows, which can often sap the life out of a small 18-inch shell.
- Ease of Use & Maintenance: A good bass drum head should be easy to seat on the bearing edge. Evans heads feature “Level 360” technology, which ensures a more even fit around the hoop, making the initial tuning process much faster and more stable over long-term use.
Once you understand these variables, you can begin to see why the Evans GMAD 18 Inch Clear Bass Drum Head is a standout choice for drummers seeking a professional edge. However, if you are still exploring the landscape of drumhead options, it’s always wise to see how it stacks up against the competition.

First Impressions and Key Features of the Evans GMAD
Upon unboxing the Evans GMAD 18 Inch Clear Bass Drum Head, the first thing I noticed was the weight and the clarity of the film. It feels significantly more “heavy-duty” than a standard G1 or Remo Ambassador. The “Clear” finish has a high-gloss aesthetic that looks sharp under stage lights. This model is essentially a single-ply version of the legendary EMAD, but with a thicker 12mil film. This is a feature that really sets it apart because it provides the “meat” of a double-ply head with the sensitivity of a single-ply.
The Externally Mounted Adjustable Damping (EMAD) system is the centerpiece here. It comes with a plastic sleeve attached to the outside of the head and two interchangeable foam rings (one thin, one thick). Setting it up is a breeze—you just seat the head, tune it to your desired pitch, and then “drop in” the foam ring that fits your sound. In my experience, compared to older versions where the damping was internal, this external system is a game-changer for quick adjustments during a soundcheck.
Key Benefits
- 12mil Film Strength: Delivers increased low-end and punch that outperforms traditional 10-mil single-ply heads.
- Exceptional Rebound: Offers a more lively and effortless feel for double-bass figures compared to dampened two-ply heads.
- Versatile Damping: Includes two different foam rings for three distinct levels of muffling (None, Thin, Thick).
- Level 360 Technology: Ensures the head sits perfectly on the drum shell for easier tuning and a wider pitch range.
Limitations
- Potentially Too Focused: Purists looking for a traditional, ringing wide-open jazz tone might find the EMAD ring too dampening even in its “naked” state.
- Single-Ply Durability: While 12mil is tough, extremely aggressive metal players may still eventually prefer a true two-ply head for maximum longevity.
A Deep Dive into the Evans GMAD 18 Inch Clear Bass Drum Head’s Performance
To truly understand why the Evans GMAD 18 Inch Clear Bass Drum Head is so highly regarded, we have to look at how it performs under real-world conditions. I put this head through its paces on an 18×14 maple kick drum, testing it across various tuning ranges and musical styles.
The 12mil Single-Ply Physics: Tone Without Compromise
The most impressive aspect of the Evans GMAD 18 Inch Clear Bass Drum Head is the choice of 12mil film. Most single-ply heads are 10mil, and while that works for toms, it often lacks the structural integrity to produce a deep fundamental on a kick drum. By bumping the thickness up to 12mil, Evans has managed to lower the fundamental pitch of the drum. When we tuned the drum “just above the wrinkle,” the result was a satisfying, deep “thump” that I usually only hear from 22-inch drums. We found that this head moves a significant amount of air, which is crucial for smaller diameters.
You can see its full feature set and user reviews to understand the durability, but from my first-hand testing, the rebound is the real star. Unlike a two-ply head where the two layers of film can sometimes create a “mushy” feel, the single 12mil layer is snappy and responsive. If you play double-bass patterns, you will notice that your beaters bounce back with more energy, allowing for cleaner, faster footwork. One user we spoke with mentioned that it allowed for “more effortless double-bass figures,” and I can confirm that the physical feedback through the pedal is superior to more dampened alternatives.
Mastering Focus with the EMAD System
The “Adjustable Damping” part of the name isn’t just marketing—it’s a functional tool that changes the character of the drum instantly. We spent hours exploring how this specific damping system improves focus across different environments. With no ring installed, the 18-inch kick has a surprisingly long sustain, making it great for acoustic jazz settings where you want the drum to “sing.” However, once you pop in the thin foam ring, the overtones are reigned in, leaving a punchy, focused attack that works perfectly for funk and fusion.
The thick foam ring is where the Evans GMAD 18 Inch Clear Bass Drum Head really “lowers the boom.” It provides a deep, solid punch that makes the 18-inch kick sound significantly larger than its physical dimensions. We found that in a studio setting, this thick ring eliminated the need for any internal pillows or blankets. This is a massive benefit because internal muffling often kills the resonance of the shell itself; the EMAD system only dampens the vibrations of the head, allowing the wood of the drum to still contribute to the overall tone. It’s a “Phat” sound that many drummers, including myself, have struggled to achieve on small kits without the use of heavy EQ.
Tuning Range and Level 360 Integration
One of the common complaints with small bass drums is that they have a very narrow “sweet spot” for tuning. If you tune them too low, they flap; too high, and they sound like a parade drum. The Evans GMAD 18 Inch Clear Bass Drum Head utilizes Level 360 technology, which is a structural design in the hoop that allows the head to sit more flush against the bearing edge. In our tests, this resulted in a much wider usable tuning range. We were able to get a surprisingly low, growling “rock” tone, but also a high-tension “bebop” pop without the head losing its character.
This versatility is a godsend for the gigging drummer. Imagine playing a jazz brunch in the morning and a wedding band gig in the evening. With the GMAD, you don’t need to change heads; you just swap the foam rings and give the tension rods a few turns. This level of adaptability, allowing you to achieve a professional studio sound with minimal effort, makes the GMAD a high-value investment. We also noted that the head stayed in tune remarkably well even after several hours of heavy hitting, which speaks to the quality of the D’Addario manufacturing process in the USA.
Durability and Long-Term Performance
Many drummers are wary of single-ply heads because they fear “denting” or stretching, especially if they use wood or plastic beaters. However, the 12mil film on the Evans GMAD 18 Inch Clear Bass Drum Head is exceptionally resilient. We evaluated the head after several weeks of intense use, and there was no noticeable “pitting” or loss of tension in the center. One user noted that they had been using their GMAD for nearly two years under heavy double-bass use, and it still sounded great. While we always recommend using a kick patch for extra security, this head is built to take a beating.
The “Clear” glossy finish also holds up well aesthetically. It doesn’t show scuff marks as easily as coated heads, maintaining that professional “new kit” look. Furthermore, the plastic sleeve that holds the foam rings is securely attached. In previous generations of EMAD heads, some users complained about the sleeve cracking or coming loose, but the modern GMAD version feels robust and well-engineered. This is why so many drummers recommend this head for smaller kits—it offers the reliability of a touring-grade product with the nuanced sound of a recording head.
What Other Users Are Saying
The general sentiment surrounding the Evans GMAD 18 Inch Clear Bass Drum Head is overwhelmingly positive, with most users praising its ability to “enlarge” the sound of a smaller kick drum. One long-time Remo user mentioned that they switched to the GMAD and were stunned by how “Phat” the drum sounded, noting that other drummers frequently ask what they are using to get such a massive tone from a 12mil single-ply. Another user highlighted the rebound, stating it allowed for more “effortless double-bass figures” compared to the EMAD II two-ply version.
However, no product is without its critics. One user felt that the head sounded “flat” compared to their previous setup, though they admitted it might have been a tuning issue or a specific mismatch with their drum shell. Another negative experience didn’t involve the head’s performance but rather shipping issues where the product arrived damaged due to poor packaging. It’s important to buy from reputable sources to ensure the head isn’t bent during transit. Despite these outliers, the consensus is that the GMAD is a top-tier choice for those who want punch without sacrificing the single-ply feel.
Comparing the Evans GMAD 18 Inch Clear Bass Drum Head to Its Top Alternatives
While the GMAD is a powerhouse for 18-inch kicks, it’s worth looking at how it compares to other industry standards. Note that while our main review focuses on the 18-inch version, these alternatives are often chosen for larger kits but offer different sonic profiles.

The EMAD2 is the double-ply version of the GMAD technology. While the GMAD uses a single 12mil ply, the EMAD2 uses two plies (7mil outer and 10mil inner). This results in a much more dampened, “compressed” sound. If you are playing extreme metal or very loud rock where you want zero sustain and maximum durability, the EMAD2 is the better choice. However, for an 18-inch drum, the EMAD2 can often be “too much” head, choking the natural resonance of the smaller shell. The GMAD is generally the better fit for the 18-inch diameter to keep some life in the drum.
2. Remo Controlled Sound 22 Inch Clear Bass Drum Head
- 22" diameter bass drum head
- Medium and heavy-duty drumhead characteristics
The Remo Controlled Sound (CS) is a classic choice featuring a 10mil film with a 5mil “Black Dot” in the center for added durability and focus. This head provides a very different feel than the GMAD; it is more “old school” and doesn’t have the adjustable damping system. It offers a great mid-range punch but lacks the deep low-end frequency of the GMAD’s 12mil film. Drummers who want a more traditional rock sound without the modern “click” of an EMAD system might prefer the Remo CS, though it requires more internal muffling (like a pillow) to achieve the same focus as the GMAD.
3. Evans EMAD Onyx 22-inch Bass Drum Head
- MAXIMIZE LOW END: EMAD Onyx bass drumhead delivers focused attack, enhanced low-end, and improved durability, making it ideal for heavy hitters
- LEVEL 360 TECHNOLOGY: The Level 360 collar design ensures balanced contact with the drum shell, allowing for easier tuning, extended pitch range, and optimum sound quality
The EMAD Onyx uses a matte black, micro-coated 10mil single-ply film. Sonically, it is much darker and warmer than the Clear GMAD. If your 18-inch kick drum is naturally very bright or “harsh,” the Onyx version can help mellow out the high-end frequencies. However, the GMAD’s 12mil clear film provides more “cut” and a sharper attack. For drummers who need their 18-inch kick to be heard through a loud guitar mix, the GMAD is the superior option. The Onyx is better suited for studio sessions where a warm, vintage-modern vibe is the goal.
Final Verdict: Is the Evans GMAD 18 Inch Clear Bass Drum Head Worth It?
After extensive testing and comparing the Evans GMAD 18 Inch Clear Bass Drum Head to other market leaders, I can confidently say it is one of the best upgrades you can make for a smaller kick drum. It successfully solves the “thin sound” problem of the 18-inch kick without sacrificing the tactile rebound that drummers love about single-ply heads. The 12mil film is the “secret sauce,” providing a depth of tone that is simply unreachable for standard 10mil heads. While it might be slightly too focused for the most traditional jazz purists, its versatility makes it a “Swiss Army knife” for every other genre.
If you are tired of stuffing your bass drum with pillows or struggling to get a professional “thump” from your bop kit, this is the solution. It is durable, easy to tune thanks to Level 360 technology, and offers instant sonic customization with the EMAD rings. Whether you are recording in a studio or playing a loud club gig, this head provides the authority your kit deserves. If you are ready to upgrade your kick drum sound today, the Evans GMAD is a choice you won’t regret. It’s time to let your 18-inch bass drum finally sound as big as your playing.
