VINCENT BACH Trumpet Mouthpiece 2C This is a mouthpiece from VINCENT BACH, a standard trumpet manufacturer. The size is 2C. Cup Depth: M (Medium) Diameter: 16.50mm Rim: MW (Medium Wide) - Gradually slopes outward. Suitable for: A large cup, powerful and brilliant sound. Ideal for those with firm lips. Personally, it's ideal for those who find the high range a little unstable with a 1-1/2C, or who find a 3C a little shallow. I think it's a mouthpiece that makes it easy to attack notes clearly. There are some shank scratches, but the rim is relatively clean.
