Made with B.20, the new Half Moon series is truly an innovation with its numereous holes on the surface. This product is like a ready cymbal on the snare and you can use it as an effect sounding hi-hat. This is a great new cymbal especially for those who play his snare and the hats at most. As for the theoric meaning of the holes on the surface, they were drilled to provide more controllable and shorther sustain. Available at 13″ and 14″ sizes.
