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
The largest common diameter in Bach's line. More lip inside the cup means bigger sound and faster fatigue if you are not conditioned.
Detail 02
Bach's middle depth. General purpose — not as dark as a B, not as bright and shallow as a D.
Detail 03
Slightly grippier on the lip than gold and slower to tarnish than raw brass. It wears through at contact points after years of playing.
Detail 04
Normal wall thickness, so it responds quicker and feels lighter than heavy-blank designs.
Detail 05
Bach's regular production line rather than a custom or hand-finished piece, which is why it costs well under boutique mouthpieces.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It is the widest common Bach rim. If you currently play a 3C or 5C and struggle with endurance, a 1C will make that harder before it helps.
The difference is mostly feel. Silver grips the lip slightly more; gold is smoother and warmer to the touch. Any tonal difference is minor next to rim and cup.
It is the cup depth. C is Bach's middle depth — a general purpose cup that sits between the deeper B and the shallower D.
No. It has a trumpet shank. Cornets and flugelhorns use different shank tapers.
