Willie's Bond 007, a mouthpiece for bass trombone. The shank is 3 (Large), compatible with standard large shank bass trombones. It is in beautiful condition with no noticeable scratches or stains. Please check the photos for details. 【Product Description】 The collaboration between Willie's and Zachary Bond, a performing artist from the German company Tine, began when he was the bass trombone player for the Malaysian Philharmonic. After serving as the artistic director of the Singapore International Low Brass Academy, he is now producing outstanding young musicians at The Hong Kong Academy for Performing Arts (HKAPA). The large rim size of 28.1mm and the extremely deep cup provide a wide and generous sound. However, it's not just a big sound; it also has a silky, fine tone. This was a necessary element to maximize the characteristics of Tine's bass trombone "Universal 007." Subsequently, due to the requests of many players, size variations of 28.5mm, 28mm, and 27.5mm were developed, further expanding the options.
