The STAGG TD-08R is a professional drum practice pad with an 8-inch (approximately 20 cm) diameter, ideal for drum practice without loud noise. It features a hexagonal wooden base with a non-slip EVA foam bottom, providing stability and shock absorption during practice. The top surface is made of rubber, offering a realistic feel and response like a real drumhead, but with much less noise. Underneath the surface, there is an 8mm (5/16") thread for easy mounting on a practice pad stand.
