This is the Heritage Series 6BL (large shank) model, imported from the prestigious British brand Denis Wick. Unlike the standard model, the combination of a thin rim and a thick cup achieves overwhelming response and a core sound. It features deep overtones and a powerful tone. The Heritage Series is famous as the brand of choice for the London Philharmonic. It is not only used in classical music, but also favored by jazz lead players such as Yamaha and Kurt Weil, and is highly regarded in a wide range of music genres. The metallic resonance unique to the Heritage is truly a "golden sound." Once you hold it, you won't want to let it go. Retail price: 51,800 yen. Cup inner diameter: 25.40 Rim width: 6.26 Bore size (throat): 6.66 Backbore shape: V-type
