Maple
A fine-grain wood with a smooth, even texture. Rich, lustrous lows with an even balance of mid tones and high frequencies have made this the all-around accepted premium shell material for years in the acoustic drum industry.
Birch
A straight-grained wood with a fine, even texture. Known for its strength and resilience, Birch provides a lively interior springboard for sound waves, creating a noticeable increase in higher frequencies.
African Mahogany
A relatively "soft" hardwood that offers a dramatic boost in lower frequencies. This bass boost effect is most likely due to its loosely packed cellulose network that creates a natural Helmholtz resonator effect in the lower frequencies.
CarbonPly
6 plies of exotic African Mahogany sandwiched between an inner and outer ply of Carbon Fiber. This distinctive combination creates a unique sonic blend between the low frequency of African Mahogany and the mid to high-range tendencies of Carbon Fiber.
