Independent shopping perspective
The Korena take
Silver-plated Schilke Group II trumpet mouthpiece in the wide 17 diameter. For established players whose chops want more room in the cup than standard sizes give.
Strong match
Who this is for
- Players with fuller lips who feel pinched on standard cup diameters
- Section and legit playing where volume of tone matters
- Strong players with the endurance to hold a wide rim up
Consider the trade-offs
When to look elsewhere
- Lead work above the staff, where narrower diameters slot easier
- Students and returning players — a wide cup is tiring to control
- Anyone after a bright, compact sound; width pushes the other way
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
Group II
Schilke's larger-diameter band. Group I numbers sit noticeably narrower, so moving between groups changes how the horn feels.
Detail 03
Rim number in the stamp
3 is the standard rounded contour. 4 is semi-flat with a cushion feel that spreads pressure and saves endurance.
Detail 04
Backbore letter in the stamp
a is tight and adds resistance for the upper register, c is standard and free-blowing, x opens the sound up.
Detail 05
The model stamp itself
Number is cup diameter, letter is cup depth, next number is rim contour, trailing lowercase letter is the backbore.
Detail 06
Silver plating
Slight grip on the lip, dulls with handling, comes back with a polish cloth. Wipe it down after playing.
Final check
Know before you order
- 01Confirm the full stamp — cup depth, rim and backbore vary within the 17
- 02Sold on its own: no pouch, case or cleaning brush
- 03Jumping several sizes wider takes weeks of chop adjustment, not days
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 17 too big for me?
It sits at the wide end of the range. If you are comfortable on a standard medium size and not straining, the jump adds work before it adds sound.
02What does a larger cup diameter actually do?
More lip vibrates inside the cup. Low register and overall volume of sound come easier, and holding the top of the range gets harder.
03Will it fit my trumpet?
Yes, it uses a standard trumpet shank. Cornet and flugelhorn take different shanks and will not seat properly.
04Silver or gold plating — does it matter?
This one is silver. It feels slightly grippier on the lip than gold and tarnishes over time, so the difference shows up in feel and upkeep.
