This series produces a deep, rich sound with exceptional projection due to its 7-ply maple shell with a darkwood stain finish. The addition of steel hoops creates precise and stable tuning to ensure a perfect sound that lasts. The line is equipped with Remo Fiberskyn Heads. Sound design and quality were the top two drivers for the Yamaha product designers. An anti-rotational slip measure on the stand, new noise control features on lug casings and tension rods, and a maple shell truly make this concert bass drum an instrument that will be the only choice for professional percussionists.
