Denis Wick Heritage 4ABL Trombone Mouthpiece [Model favored by the London Philharmonic] [Retail Price: ¥51,700] This model is favored by trombone players in world-class orchestras, including the London Philharmonic Orchestra. The cup size is a slightly large 4 (inner diameter 26.00mm), but it excels in ease of handling in the high register, and is particularly popular for 1st parts in wind bands and film music. This time, I will be selling this mouthpiece to someone who needs it, as I am moving to the 4AL model of the same series to aim for further improvement. • Model Name: Denis Wick Heritage 4ABL • Finish: Gold-plated • Shank: Large shank • Cup Inner Diameter: 26.00mm • Throat Diameter: 7.38mm • Condition: Beautiful condition, used only a few times. There are no noticeable scratches or plating剥がれ. This is a masterpiece that combines high-pitched responsiveness and depth of tone. If you are looking for one, please consider it.
