Original price: 47,300 yen This is a very good mouthpiece, but I am selling it because it doesn't fit my instrument. It has been used a few times, just for testing. Denis Wick Aaron Tindall model mouthpiece The rim is all WD24 rim of Warren Deck, Aaron Tindall's teacher, and is the same size, with a different cup and throat size, the No. 7. The cup is said to be equivalent to Perantucci PT-65. The WD24, which is the base of the rim, is an expanded version of the Bach 24AW. It is smaller than the popular large rims, but it is standard by modern standards. It doesn't feel cramped and I think it will respond well even with a large instrument. Compared to my Jardine WD24, the rim feels a little rounder, and I feel it is a mouthpiece with a soft and comfortable feel. The No. 7 cup has a moderate feel, and unlike the WD24, you don't feel like your breath is being taken away, and it feels good to blow. It gives the impression of a versatile standard model like the No. 67, a legitimate evolution of the 24AW. It has a transparent feel that doesn't make you aware of the mouthpiece. It is a model for F tuba, but I thought it would also fit BC tuba. Cup inner diameter: 32.80 Bore size (throat): 8.00 For soloists of F tuba. Clear sound, recommended for solo and chamber music. It features a rich and colorful tone. Type... Tuba Accessories/Parts... Mouthpiece
