Construction and Materials of Shell Packs
Wood Types: The choice of wood is a crucial factor in determining the sound and quality of a shell pack. Common woods used include maple, birch, oak, and mahogany. Maple is renowned for its balanced tone, offering a warm midrange and clear highs. Birch, on the other hand, produces a brighter and more focused sound with enhanced attack. Oak provides a robust and powerful tone, while mahogany imparts a deep, rich, and resonant low end. The grain structure and density of each wood type contribute to its unique sonic properties. For example, maple’s tight grain helps in producing a more even and controlled sound.
Shell Layers and Thickness: Many modern shell packs feature multiple layers of wood. These layers can be glued together in different configurations. Some shells have thin layers, which can result in a more responsive and resonant sound as the drum vibrates more freely. Thicker shells, on the contrary, tend to offer a more focused and powerful sound with increased projection. The number of layers and their thickness are carefully engineered to achieve the desired tonal balance and durability. For instance, a 6-ply maple shell might have a thickness of around 7mm and provide a good combination of resonance and strength.
Finishing and Coating: The finishing of the drum shells not only affects their appearance but also has an impact on the sound. Lacquer finishes are popular as they allow the natural tone of the wood to shine through. They can enhance the resonance and warmth of the drums. On the other hand, wrap finishes, such as vinyl or laminate, offer a wide range of colors and designs. While wraps may slightly dampen the natural resonance compared to lacquer, they provide durability and protection to the shell. Matte finishes are also available, which give a more understated and modern look while maintaining good sound quality.
Tonal Characteristics of Shell Pack Drums
Low-End Response: The bass drum in a shell pack is a key contributor to the low-end sound. The size of the bass drum, along with the wood and construction, determines the depth and punch of the low frequencies. A larger bass drum, say 22 inches in diameter, made of mahogany, will produce a deep, thundering low end that is ideal for rock and heavy music genres. The thickness of the drumhead and the tuning also play a significant role. A single-ply, thicker drumhead tuned low can enhance the sub-bass frequencies, while a thinner head might offer a more defined and articulate low end.
Midrange Clarity: The tom drums in a shell pack are responsible for the midrange frequencies. Woods like maple and birch excel in providing clear and defined midrange tones. The depth and diameter of the toms affect the midrange character. Shallower toms, for example, tend to have a more focused midrange with a quicker decay, which is suitable for faster-paced music styles like funk and jazz. Deeper toms can offer a more resonant and sustained midrange, adding richness to ballads and slower pieces. The choice of drumsticks and the striking technique also influence the midrange clarity, with softer sticks producing a more mellow midrange and harder sticks bringing out more attack.
High-End Sparkle: The snare drum is the main source of high-end frequencies in a drum set. Shell pack snares can be made of various materials, including metal and different woods. A metal snare, such as a steel or brass one, will produce a bright and cutting high end with excellent projection. Wooden snares, like maple or walnut, offer a more balanced high end with a touch of warmth. The snare wire tension and the type of snares used (such as 20-strand or 42-strand) also affect the high-frequency response. A tighter snare wire tension will increase the crispness and sizzle of the high end, while a looser tension gives a more subdued and airy feel.
Sizes and Configurations of Shell Packs
Bass Drum Sizes: Shell packs come with a variety of bass drum sizes. The most common sizes are 20 inches, 22 inches, and 24 inches. A 20-inch bass drum is more compact and is often favored in smaller drumming spaces or for more portable setups. It offers a tighter and more focused low end, suitable for genres like jazz and fusion. The 22-inch bass drum is a popular all-rounder, providing a good balance of power and control. It is widely used in rock, pop, and many other mainstream music styles. The 24-inch bass drum is the largest of the common sizes and delivers a massive and booming low end, perfect for heavy metal and large concert setups.
Tom Tom Sizes and Placement: Tom toms also have different size options. Common sizes include 8 inches, 10 inches, 12 inches, 13 inches, and 16 inches. The smaller toms, like the 8-inch and 10-inch, are used for higher-pitched accents and fills. They are often mounted on the bass drum or on a separate stand. The 12-inch and 13-inch toms are mid-range toms that provide a good balance of pitch and volume. The 16-inch tom is a floor tom, which offers a deeper and more resonant sound. The configuration of the toms can vary, with some drummers preferring a traditional setup with the toms arranged in a specific order, while others opt for more experimental and asymmetrical setups to achieve unique sonic and visual effects.
Snare Drum Sizes and Styles: Snare drums in shell packs usually range from 14 inches in diameter. The depth can vary from 5 inches to 8 inches or more. A shallower 5-inch snare might have a more responsive and crackling sound, ideal for quick and precise playing. A deeper 8-inch snare can produce a more powerful and full-bodied sound, suitable for heavier music. There are also different styles of snare drums, such as piccolo snares (with a smaller diameter, usually around 10 inches) that offer a very high-pitched and sharp sound, and marching snares that have a more robust and durable construction for outdoor and marching band use.
Customization and Upgrades for Shell Packs
Hardware Selection: Drummers can customize their shell pack setups by choosing the appropriate hardware. This includes drum stands, pedals, and mounts. High-quality stands with adjustable features allow for precise positioning and stability. A double-braced stand is more durable and can handle heavier drums. The bass drum pedal is a crucial component, and options range from basic single-chain pedals to high-end double-chain or direct-drive pedals. Direct-drive pedals offer a more immediate and responsive feel, while double-chain pedals provide more power and durability. Mounts for tom toms can be adjustable, allowing for different angles and heights to optimize playing comfort and sound projection.
Cymbal Pairing: Selecting the right cymbals to complement a shell pack is essential. Cymbals come in various types, such as hi-hats, crash cymbals, and ride cymbals. The size and thickness of the cymbals affect their sound. A thinner crash cymbal will have a more washy and open sound, while a thicker one will produce a more explosive and cutting crash. Hi-hats with different degrees of closure and weights can offer a wide range of chick and sizzle sounds. The choice of cymbal brand and series also plays a role, as different manufacturers have their own unique sonic signatures. For example, some cymbals are known for their bright and shimmering sound, while others are more focused on warm and dark tones.
Drumhead Upgrades: Upgrading the drumheads can significantly improve the sound of a shell pack. There are single-ply, double-ply, and specialty drumheads available. Single-ply heads are more responsive and offer a more natural tone, but they may be less durable. Double-ply heads are thicker and provide more volume and projection, making them suitable for louder playing situations. Specialty heads, such as coated heads that reduce overtones or clear heads that enhance resonance, can be chosen based on the desired sound. Additionally, some drumheads have built-in muffling systems or are designed for specific music genres, like jazz or rock.
