YAMAHA Tuba Mouthpiece 67C4 Quoting from the manufacturer's website: This is an all-around model, ideal for B♭ and C tubas. It produces a consistent, calm tone with a rich, powerful sound. Photographed near a window in natural light. The photographer's hands are reflected, causing some areas of the image to appear slightly skin-toned. #mouthpiece #tuba #tubamouthpiece #YAMAHA
