All shells include Gretsch "302" 3mm/double-flanged hoops, Lightning throw off and butt plate, "Snap-in" drum key holder, 20-strand snare wire and Gretsch Permatone drum heads. The Brass shells resonate with classic, musical tones and are extremely versatile. The "302" hoops provide a timbre that is more open and ambient than traditional Gretsch die-cast hoops.
