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
Mid-size rim for this line — smaller than the 1 and 2W, same diameter as the 3C.
Detail 02
Slightly wider than the 3.70mm models in the series, so a bit more air moves before the sound compresses.
Detail 03
Holds the sound centered rather than spreading it, unlike the V-type backbore on the 4E and 5E.
Detail 04
Narrow rim. More flexibility and slotting feel, less cushion across a long set.
Detail 05
Same cup diameter, near-identical rim. The E is bright and projecting; the C blows freer and sounds warmer.
Detail 06
Firm, cool feel against the lip. It tarnishes, so wipe it down rather than letting residue build.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It rewards a developed embouchure and steady air. In this same series the 4B is the beginner piece — warm tone, plays very easily.
Identical 16.75mm cup and near-identical rim. The 3E is brighter and crisper with more projection. The 3C is free-blowing with a warm sound and easier response.
It is built for the upper register and makes high playing easier to project. It sharpens what you already have; it does not replace range practice.
It is a trumpet mouthpiece and takes a trumpet receiver. Cornet and flugelhorn use different shanks and will not accept it.
