26.40mm cup diameter
One of the widest in this series. More lip vibrates, favoring low-register breadth over endurance and high-range security.

1/2
Independent shopping perspective
The Korena take
Gold-plated euphonium mouthpiece in the SM3U size — large shank, 26.40mm cup. For players wanting a wide cup and open blow.
Strong match
Who this is for
- Euphonium players who want more cup diameter for a broad low register
- Large-shank euphonium receivers on pro-level horns
- Players whose lips react badly to silver plating
Consider the trade-offs
When to look elsewhere
- Medium-shank receivers — this is the large-shank SM3U
- Players who fatigue on wide rims during long sessions
- Baritone horn players needing a smaller cup
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
Large shank
Must match a large-shank euphonium receiver. It will not seat correctly in a medium-shank horn.
Detail 03
7.40mm throat
An open throat. Lets more air through for volume and a fuller sound, at the cost of more resistance feedback for the player.
Detail 04
V-type backbore
Tapers gradually, generally producing a darker, rounder tone than a more conical backbore.
Detail 05
6.30mm rim width
Medium rim. Spreads pressure over enough lip for comfort without the pinpoint control of a narrow rim.
Detail 06
Gold plating
Warmer to the touch and non-reactive, so it suits players who get irritation from silver. Softer surface than silver plating.
Final check
Know before you order
- 01Confirm your euphonium takes a large shank before ordering this SM3U
- 02Cup diameter changes embouchure feel — expect an adjustment period
- 03Gold plating wears with heavy use and is not repairable at home
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my euphonium?
Only if the receiver takes a large shank. The SM3U is large shank; medium-shank horns need the SM3MU instead.
02What is the difference between SM3U and SM4U?
Cup diameter. The SM3U is 26.40mm, the SM4U is 26mm. Both share the 6.30mm rim, 7.40mm throat and V-type backbore.
03Gold or silver plating — does it change the sound?
Plating mainly changes feel and skin reaction. Gold runs warmer against the lip and suits players sensitive to silver.
04Is this a good size to start on?
The 26.40mm cup is on the wide side. Players building endurance often find a smaller cup like the SM5U or SM6U easier to sustain.
