Evans G2 Coated Bass Drum Heads feature greater durability and projection power than G1 Coated Heads, thanks to their two-ply design. Each ply is 7 mils thick - so 14 mils total - that grant you very balanced depth, sustain, and attack.
Coated G2 heads are known for tons of resonance with only a bit of attack up front, making them excellent for quieter genres of music and the recording studio. The coated surface has increased warmth.
