Schilke Tuba Mouthpiece 69C4 Silver Plated Used for practice for about 3 years. There are scratches on the rim as shown in the photo, and there appears to be a slight distortion on the outside of the shank. Also, there is some clouding and surface scratches due to the aging of the silver plating. Please check the photos. Overall, there is no major deformation or dirt, but there is a feeling of use, so I will sell it at a low price. 69C4 / 32.76mm / The combination of a comfortable rim and a not-too-deep cup creates a tone with excellent characteristics, and the entire range sounds good.
