Yamaha has a knack for creating killer birch drums. Whether it is the Recording Custom, Absolute Birch, or Stage Custom, Yamaha birch drums have this uncanny ability to make drummers week in the knees. The 100% birch shell gives these drums a unique sound that is sharp and punchy while still having the ability to rumble and resonate. The Yamaha Stage Custom Birch kits are then fitted with Yamaha's signature lugs, triple-flange hoops, YESS mounting system, and more. The YESS system provides rock solid stability while allowing you to position your drums any way you'd like. In addition they YESS system makes minimum contact with the shell itself. The Bass Drum features die-cast claw hooks with rubber insertion plates and telescoping legs. 100% Birch Shells The shell is a key factor in a drum's ability to "rumble," or resonate. Accordingly, the Stage Custom employs 100% birch - a classic in the realm of high-class drum kits. Moreover, with its six-ply structure the Stage Custom accurately conveys the vibrations produced at the impact surface, achieving performance that overwhelms anything in its class. Yamaha Enhanced Sustain System - YESS The secret of our YESS system is twofold: First, it provides minimum contact of hardware with shell; second, it connects that hardware at the nodal point* of the drum - the point at which it will not interfere with shell vibration. Nylon bushings on rod clamps afford maximum stability. The YESS system permits toms to be placed close together, and does not interfere with quick head changes. On floor toms, our YESS system offers wide open sustain while keeping toms stable under the heaviest strokes. * Nodal point mounting is patented by the Noble & Cooley Drum Company. Ball Mount & Clamp A tribute to Yamaha design technology, our original ball mount and clamp has gone through very few modifications over the years. A large, ultra-hard resin ball sits in an attractive chromed housing, held in place with a titanium ergonomic wing bolt. It is the ultimate drummer-friendly mount, offering non-slip positioning virtually anywhere the drummer can imagine. Additionally, it permits tuning of the bottom head by simply rotating the drum.
