• Using a single-ply of Evans ShockWeave Mesh combined with Kinetic Transfer Foam™ (KTF), dB One bass heads transfer impact energy into sonic vibrations for dynamic, low volume drumming. • Special Impact Patches reinforce the striking surface of the bass head, while enhancing the audible attack and articulation. • Evans dB One low volume bass drumheads maintain true acoustic drum tone, with a natural feel. | • Our mesh drumheads allow you to play as you normally would with a traditional drumhead, without changing your technique, and achieve a similar feel and sonic response. • All Evans drumheads are designed, engineered, and manufactured in the USA. |
