Consistency is the defining trait of the Evans EMAD UV2 bass drumhead, especially under demanding playing conditions. Evans’ patented UV coating is layered over two plies of 7-mil film to support impact resistance while helping preserve tonal integrity over the life of the head. EMAD UV2 heads offer a medium brightness and the flexibility to adjust attack, focus and sustain using EMAD, making it easier to dial in response without changing heads. An internal overtone control system keeps the sound controlled and focused, while Level 360 Technology helps ensure even seating and reliable tuning across different shells. Available in 16", 18", 20", 22", 24" and 26" sizes, these heads are designed to perform consistently across a wide range of bass drum setups.
