This is a Willie's French horn mouthpiece, model S78 M2 S AX. There are some scratches around the shank from insertion and removal, but overall, it appears to be in good condition. *Please note that I will be unable to ship items from November 10th to November 12th due to circumstances.* The specifications are as follows: Inner rim diameter: 17.8mm Rim shape: S rim (gradually sloping outwards) Cup shape: Slightly U-shaped V cup (similar to Mac Williams 2) Throat diameter: 4.2mm Cup appearance: S blank (light type: thinned rim underside) Shank: AX (designed for Alexander and double-taper Yamaha horns) Because the cup is slightly deep, it produced a calm, soft tone. While it's difficult to produce a harsh tone, it offers flexibility and blends well with other instruments and sections. Willie's mouthpieces have a smoother feel than any other manufacturer's, and while they feel soft, they surprisingly stay in place and are less tiring. I've decided to sell it because I've compared it with several others and chosen a different mouthpiece as my main one. Current new price: 33,000 yen I plan to keep it for myself if it doesn't sell, so there are no plans to lower the price.
