Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes. It sits mid-range in cup depth and rim size, which is why it works as a starting point and as a reference when you later compare other sizes.
No. French horn shanks are a different diameter and length entirely. It will not seat in a trumpet, cornet, or any other brass receiver.
Lower numbers are larger. A Bach 7 is smaller than a 3 and larger than a 12.
Warm water and a mouthpiece brush. Avoid harsh solvents or dishwashers, which can dull the plating over time.
