Detail 01
.690 inch cup diameter
Large. Rim high point sits nearer the center, so it feels smaller in play than the number suggests.

Independent shopping perspective
The Korena take
Gold-plated Schilke 18B4 trumpet mouthpiece: large .690" cup with a medium-shallow B cup and semi-flat rim. For classical players who need commercial brightness.
Strong match
Who this is for
- Classical players doubling on commercial or big band gigs
- Large-diameter players who want sparkle without going shallow
- Long sets where a semi-flat rim preserves endurance
Consider the trade-offs
When to look elsewhere
- Players with smaller embouchures; .690" is a lot of rim
- Pure lead work — an A cup gets higher, easier
- Anyone wanting a dark symphonic tone; the B cup brightens things
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
Medium-shallow B cup
Adds resistance and sparkle over a standard C cup, while keeping enough cup volume for real tone.
Detail 03
Number 4 semi-flat rim
Broad, flat bearing surface distributes pressure. Comfortable in the upper register over long playing sessions.
Detail 04
26 throat
Schilke's standard throat. Normal resistance — not the opened 27 throat found on the A-cup lead models.
Detail 05
Gold plating
Smoother, slicker on the lip than silver. An option for players whose skin reacts to silver plating.
Detail 06
Group II sizing
Schilke's large-diameter range, .674" and up. A different world from the Group I .630–.665" pieces.
Final check
Know before you order
- 01Mouthpiece only — no trumpet, case, or pouch included
- 02Fits standard small-shank trumpet receivers; check yours
- 03Jumping to .690" from a medium rim takes real adjustment time
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01How does the 18B4 compare to the standard 18?
Same .690" diameter. The 18 has standard characteristics and a rich, brilliant tone; the 18B4 swaps in a medium-shallow B cup and semi-flat #4 rim for more resistance and upper-register comfort.
02Is .690 inches too big for me?
Depends on your embouchure strength. The 18's rim high point sits closer to the center, so it plays smaller than .690" implies — but if you're on a .660" piece, expect a real adjustment.
03Can I use this for orchestral playing?
The diameter suits it, but the medium-shallow B cup adds brightness and resistance. For a darker orchestral sound, the deeper C or D cups in Group II are a closer match.
04Why does the gold version cost more than silver?
Gold plating is the more expensive finish. The rim, cup, throat and backbore are identical to the silver version — you're paying for the plating and its smoother feel.
