The DDrum F1820 18" & 20" Deccabons are for when enough is NOT enough! They have a black finish, have fiberglass shells, are 6" in diameter, and come in lengths from 6" to 24". These are the perfect accent to your kit. Deccabons' pitch are determined by shell depth, rather than diameter. Mount them in traditional descending order, or place them around the kit for unexpected accents. Expand your sonic palette!
