Group II diameters (.674"–.720")

Independent shopping perspective
The Korena take
Schilke Group II trumpet mouthpiece, 15B, gold plated. Larger diameter with a brilliant B cup, aimed at players who want projection without going shallow.
Strong match
Who this is for
- Section players wanting volume with some edge in the sound
- Classical players needing a commercial brightness
- Trumpeters whose embouchure supports a .674" rim
Consider the trade-offs
When to look elsewhere
- Developing players — the larger diameter demands a set embouchure
- Screaming lead work above the staff; a shallow A cup suits better
- Anyone needing a budget spare mouthpiece
What matters in use
The specifications, translated
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 02
15B cup at .674"
Smallest diameter in Group II with a B cup — brighter than the standard 15, but same rim footprint.
Detail 03
B cup shape
Medium-small and shallower than a C. More resistance and brilliance, which helps the sound carry over a band.
Detail 04
26 throat
The standard Schilke throat. Balanced resistance; the 27 models trade openness for high-register feedback.
Detail 05
Gold plating
Smoother and slicker on the lip than silver. Useful if silver irritates your skin, and it wears well.
Detail 06
Number 3 vs number 4 rim across the range
3 is standard contour. 4 is semi-flat and cushions pressure, which is why the endurance-focused models use it.
Final check
Know before you order
- 01Mouthpiece only — no pouch or case included
- 02Jumping from a Group I size to .674" changes your setup noticeably
- 03Gold plating carries a real price premium over the same model in silver
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What is the difference between the 15 and 15B?
Same .674 inch diameter and 26 throat. The 15B has a B style cup, which is shallower and produces a more brilliant sound than the standard 15.
02Is gold plating worth the extra cost?
It matters most if silver irritates your lip or you want a slicker feel. Cup depth and rim shape affect your playing far more than plating.
03Is 15B too big for a high school player?
It sits at the small end of Group II. Workable for a strong player, but the larger diameter takes more embouchure control than a typical student size.
04Does it work on Eb or piccolo trumpet?
It uses the standard trumpet shank so it physically fits. Schilke builds specific models for those horns, like the 16B4 for Eb and the 11Ax for piccolo.
