The Alu Bell features a dome-shape and narrow striking edge. Aluminum creates a clear and musical bell-like response and is very lightweight to produce long, sustaining notes. Every Alu Bell is individually created using traditional sand-casting methods, so each piece has a rough surface. Aluminum Bells are comparatively thick and have an unfinished look, but their tone is very sweet and musical, with great sustain. They are also quality protected by the Sabian one-year warranty.
