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
Moderate for tenor. Small enough to control in the upper register, big enough to fill out low notes.
Detail 02
On the tighter side. More back-pressure, which helps stability and slotting but caps ultimate volume.
Detail 03
Fits large-bore tenor and bass trombones only. A small-shank horn needs a different mouthpiece or an adapter.
Detail 04
Not the wider semi-flat 4 rim of the 47C4. Slightly more bite and articulation clarity, slightly less cushion.
Detail 05
Cooler and more slippery than gold. Some players with metal sensitivities react to it.

Product questions
Straight answers to the questions shoppers most often ask about this product.
Only if it takes a large shank mouthpiece, typical of large-bore tenor and bass trombones. Student and small-bore tenors take small shank.
The 47 is about .018 inch larger in cup diameter. The 46 is aimed at beginners with a flexible semi-flat rim; the 47 gives more tone and works from student through professional playing.
For heavy orchestral tenor work most players want more — the 51, 52, or 53 offer larger diameters and bowl cups for a richer, fuller sound.
Same basic design and near-identical diameter. The 47C4 adds a slightly wider semi-flat number 4 rim for more cushion and endurance.
