5-piece acoustic drum kit. The Stage Custom series has been setting the standard since 1995, offering a truly professional drum kit at an affordable price. This kit features 6-ply 100% birch hulls with a 45-degree rim. The staggered diagonal stitching allows for a thin hull that is strong and built to last. The Yamaha Stage Custom Series features a beautiful high gloss lacquered finish and has the legendary YESS system that maximizes drum resonance by providing minimal contact of the hardware with the hull and connects the hardware to the nodal point of the drum, where it does not interfere with the vibration of the hull.
