The Meinl 15” Polyphonic Hi-hats are expressive through their varying profile with thin edges and a thicker, unlathed bell. Their medium thin weight in the bow allows them to be very versatile and live up to their Polyphonic name. When closed, these hi-hats deliver tight grooves with just the right balance of attack and air underneath. When you need power, open them up to hear the unlathed bell add a dark roar to the wash. The bell also provides the foundation for a solid chick with your foot.
