The Yamaha Recording Custom 22″ 4pc Shell Pack is the peak of all drumming. Renowned for its impressive recording and performance capabilities the Recording Custom has set the benchmark for excellence for over 30 years. Its one of the most recorded drum kits in history and its clear to see why. The Recording Custom features birch shells with a pristine interior and exterior finish. These shells deliver a sound that seems pre-EQd – perfect for studio and multi-mic drumming. Even when playing this kit with no amplification or microphones it will hold is own with a great level of power and tone to spare. The Yamaha Recording Custom kit features the Y.E.S.S system providing maximum resonance for your toms. This allows each drum to sing with maximum tone eliminating any unwanted sound. All birch shells provide a studio-ready sound Birch shells produce a lower fundamental tone than maple. Their crisp sound quality with short attack decay makes them optimal for recording situations. Our Air Seal System shells feature select birch wood cut in plies positioned with staggered diagonal seams and sealed together with evenly distributed air pressure. This process ensures that every drum shell is in round and of uniform thickness while providing superior tone quality and durability. Hi-tension lugs offer effortless tuning Precision-machined lug nuts provide noise-free control due to their springless casing design. Manufactured as genuine one-piece units our high-tension lugs have established one of the principal trends in modern design. Mounted toms and floor toms equipped with YESS Mounts Long found on our high-end drum kits our original YESS (Yamaha Enhanced Sustain System) allows attachment of the drum to the tom holder without the need of a hole in the drum shell for the rod to pass through. The YESS clamp is attached to the shell at the nodal point with two bolts so as to allow the shell to vibrate freely without degrading the shells dynamic range and sustain. The nodal point is the location on a shell with the least amount of vibration allowing for the mount to have minimal affect to the resonance of the shell.
