Denis Wick Tuba Mouthpiece 3L. Silver-plated. Cup inner diameter: 31.25mm, V-cup bottom. It has good response in the low register and a deep, mellow tone. It feels comfortable on the mouth and when playing, and I think it suits both B♭/C tubas and E♭ tubas. I have kept it with care, so there are no dents or major scratches. The silver plating is also in beautiful condition. Please consider purchasing it. Thank you for looking.
