Detail 01
.633 inch cup diameter
Small even within Schilke's small group. Less lip in the cup means easier high notes and a narrower sound.

Independent shopping perspective
The Korena take
Gold-plated Schilke 7B4 trumpet mouthpiece. Small .633 inch diameter with a semi-flat rim, made for thin-lipped players who want endurance and a brilliant tone.
Strong match
Who this is for
- Players with thin lips who float on standard rims
- Long sets where endurance matters more than tone volume
- Trumpet parts sitting high in the staff
Consider the trade-offs
When to look elsewhere
- Players wanting a big, broad orchestral sound
- Anyone comfortable on a standard 7C-size rim already
- Thick-lipped players who need more rim real estate
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
Number 4 rim
Semi-flat and wider. Spreads pressure across the lip, which is where most of the endurance gain comes from.
Detail 03
B cup
Medium-small conical depth. Brighter and more focused than a C cup, with less low-register weight.
Detail 04
26 throat
Schilke's standard bore, not the tighter 27 used on the A-cup lead pieces. Blowing feel stays conventional.
Detail 05
Gold plating
Slicker and warmer against the lip than silver, and the option if silver plating irritates your skin.
Detail 06
Group I sizing
Schilke's smaller diameter range. Changing groups is a real embouchure change, not a minor tweak.
Final check
Know before you order
- 01Mouthpiece only. No trumpet, case, or pouch included.
- 02Small diameters can choke low register if your lips don't suit them.
- 03Gold plating wears at contact points over time. Handle by the shank.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 7B4 a lead mouthpiece?
Not strictly. It's small with a semi-flat rim for endurance and a brilliant tone, but Schilke's dedicated lead pieces use shallow A cups and tight a-backbores, like the 13A4a.
02What does the 4 in 7B4 mean?
The rim number. A 4 rim is semi-flat and wider than the standard 3, spreading pressure over more of the lip for better endurance.
03Will a smaller mouthpiece give me higher range?
It can make high notes easier by putting less lip in the cup, but it also thins the sound and can make low register harder. Fit matters more than size.
04How does this compare to the 7B4 in silver?
Dimensions are identical. Gold plating feels smoother and warmer on the lips and suits players who react to silver.
