Sabian AAX AAXtreme Chinese. Extra-fast and terrifically punchy response is raw, dirty, very tight - almost Kang-like - and super loud for maximum accent. Thin. Like stainless steel, AAX is cool, modern, and extremely efficient. Tap with your finger or thrash with a stick, Auto-Focus Response maximizes sensitivity, equalizes high- and low-pitch levels, and purifies sounds by filtering out conflicting overtones.
