Horn Mouthpiece Yamaha (YAMAHA) 30C4 Retail Price: 6,380 yen Engraving: YAMAHA JAPAN 30C4 Used only for test playing (2-3 times), I believe it is in very beautiful condition overall. *Please check the details in the images* With a standard inner rim diameter and a U-cup with a standard depth, combined with a slightly narrow throat, this mouthpiece is very easy to play across the entire range, including the high register. The slightly flat and not-too-thick rim feels comfortable on the lips and is easy to lip slur. Loved by advanced players, it is a versatile mouthpiece suitable for ensembles to large orchestras. ・Cup Inner Diameter: 17.28mm ・Bore (Throat): 3.98mm (Standard) ・Cup: U-cup ・Rim Thickness: Standard *Catalog explanation: "Due to the moderate rim inner diameter and U-cup, it features a sound with a sense of speed. It has moderate resistance and a powerful, rich sound." Due to the nature of its use as a "mouthpiece," there will inevitably be minor scratches and marks due to contact during instrument attachment, playing, 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 at a new level, or if you are particular about the details, please consider carefully before purchasing. I am selling it at a lower price than the new price, considering it is used, so please understand this point. Thank you for your understanding and consideration. [French Horn]
