Slightly wider rim than the common 7. More lip vibrates, giving a bigger sound but shorter endurance at first.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
Slightly wider rim than the common 7. More lip vibrates, giving a bigger sound but shorter endurance at first.
Detail 02
Bach's medium depth. The all-purpose choice: enough body for concert work without losing the upper register.
Detail 03
Grippier on the lip than gold and durable. Some players react to silver against skin.
Detail 04
Bach's production line rather than hand-finished. Consistent enough that a replacement feels the same.
Detail 05
Fits standard Bb and C trumpets. Cornets and flugelhorns take different shanks and will not accept it.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
Yes, slightly wider in rim diameter with the same C cup depth. It gives more room for low notes and a fuller sound.
Only if the 7C feels cramped in the low register. If your range and endurance are fine, there is no need to change.
No. This is a trumpet shank. Cornets and flugelhorns use different taper sizes and need their own mouthpieces.
Silver feels grippier and firmer on the lip. Gold feels smoother and suits players who react to silver. Tone difference is minimal.
