6 plies in the rack tom shells and 8 plies in the floor tom and bass drum shells provide an amazingly balanced sound, unprecedented for this category.
After thorough research, Pearl discovered that the inner ply of a drum shell has the greatest effect on the tonal quality of the drum. Therefore, putting Birch on the inner ply of these drums gives them a naturally "EQ‘d," punchy tone with enhanced projection and sustain.
Two ply heads are easier to tune, and deliver a full, powerful sound right out of the box. Vision is the only series in its category to be packaged with two ply heads.
