The heavier weight of the Meinl Mb10 Heavy Soundwave Hi-Hats increases their volume and raises their pitch. They have a powerful and sizzling open sound with a full-bodied, fat chick. The wavy bottom eliminates air lock for maximum clarity. Meinl's Mb10 hi-hat cymbals are made out of B10 bronze alloy. The fundamental sonic characteristic of this alloy is responsible for an extremely modern and sophisticated sound. An extensively lathed and highly polished cymbal surface results in a modern look and plenty of attitude.
