Sabian AAX Studio Crash Cymbals offer a thin design with a brilliant finish, and small bell for quick response, and tonally full glassy and shimmering accents. Sabian AAX cymbals deliver pure, bright shimmering tones. 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.
