Horn Mouthpiece Tilz D4 A Retail Price: ¥17,600 Engraving: Spezial Bruno Tilz A (American Shank) Overall, I believe it's in relatively good condition. There are some minor scratches and scuff marks in places, but I didn't feel any hindrance while playing. - Cup Inner Diameter: 17.5mm - Bore (Throat): 4.0mm - Cup: MS (Medium Shallow, U-cup with a slightly V-cup feel) - Rim Thickness: 4.4mm MB (Standard rim thickness) - Although the cup is somewhat shallow, it produces a rich tone, and is particularly easy to play in the high register. I believe it allows the instrument to resonate richly even with relatively less air. Also, it's less tiring even during long performances, and I think it's a well-balanced mouthpiece across the entire range. If you are looking for one, or if you are interested in purchasing, I hope you will consider this opportunity. ※ Due to the nature of mouthpieces, there will inevitably be minor scratches, etc., due to contact during instrument attachment, care, cleaning, and wiping. Also, I have confirmed that these do not affect the performance at all before listing. If you are looking for a perfect item on par with a new one, or if you are particular about the details, please consider carefully before purchasing. I am selling it at a low price (less than half the retail price) considering it is used, so I would appreciate your understanding. Thank you for your consideration and understanding. [French Horn]
