S.E. Shires 2G Vintage Large Bore, MSRP: ¥25,000 This is a mouthpiece for bass trombone. It has only been attached to an instrument a few times, so it's in very good condition. It's a great size for those who find 1 1/2 too deep and 3G too light. It's a 2G size from the Vintage series. The manufacturer's description is as follows: S.E. Shires has released its long-awaited custom mouthpieces. Based on the vintage American mouthpieces of yesteryear, these were developed through research by Steve Shires, the maker and player himself, and the Shires staff. Japanese demand was also considered during the design process. In the United States, where they were released ahead of other markets, orders were concentrated, and the initial production run sold out. The Shires company is receiving inquiries daily from dealers and professional musicians around the world, making it a big topic of conversation in the wind instrument industry.
