Using the Evans dB One Rock Tom Pack is a breeze. Just attach the 10", 12", and 16" drumheads to your drums as you would with regular heads. You can start practicing right away and enjoy quiet drumming without sacrificing the real drum sound. When it comes to maintenance, keep the drumheads clean. You can use a soft, dry cloth to wipe off any dust or debris. Avoid using harsh chemicals or abrasive materials as they can damage the mesh. Also, store the drumheads in a dry and cool place when not in use. As for the Impact Patches, they are quite durable, but be gentle when striking them to ensure long - lasting performance. And remember, this pack is mainly designed for practice, so if you're using it for a full - scale concert, you might want to consider other options.
