Bach's regular production line, so replacements and matching sizes stay easy to find.
Detail 05

Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. The 1-1/2C has a noticeably wider cup diameter with a similar cup depth. Expect a fuller low and middle register and more air demand.
Only if your cornet takes a trumpet-shank mouthpiece. Most cornets use a smaller shank taper and need a cornet mouthpiece or an adapter.
Silver has more drag against the lip, which many players read as better grip. Gold feels slicker and suits anyone reactive to the metals under plating.
It is large for a first mouthpiece. Most beginners start smaller and move up once their embouchure and air support are established. Ask your teacher first.
