YamahaStandard Series Small Shank Trombone Mouthpiece in Silver 48D
Independent shopping perspective
The Korena take
Small-shank trombone mouthpiece with a Bach 6-1/2AL rim and a deeper cup. For small-bore tenor players who want more warmth and low-register body.
Strong match
Who this is for
- Small-bore tenor trombone players already comfortable on a 6-1/2AL rim
- Adding low-register weight without changing the rim feel you know
- Concert band parts that sit in the middle and low register
Consider the trade-offs
When to look elsewhere
- Large-shank horns — bass trombone receivers will not take it
- Lead players chasing bright, easy high notes
- Alto trombone doublers, who want the shallow-cup 48A instead
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
Deeper cup than a standard 48
Darker tone and a fuller bottom end, paid for with endurance and high-register ease.
Detail 03
Bach 6-1/2AL rim size
The most common student-to-intermediate rim, so coming off a stock 6-1/2AL feels familiar immediately.
Detail 04
Silver plating
Slick, firm feel on the lip and easy to keep clean. Skip it if silver irritates your skin.
Detail 05
48A in the same series
Same rim with a shallow cup for alto trombone, if you double on alto.
Detail 06
51 and 52 sizes above it
Bach 5G-class rims. Move up if this one feels small under a big sound.
Final check
Know before you order
- 01Confirm your leadpipe is small shank; it will not seat in a large bore
- 02Sold as a single mouthpiece, nothing else in the box
- 03A deeper cup takes more air — give it a week before judging
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my bass trombone?
No. It is a small-shank piece for small-bore tenor trombones. Bass trombones use a large shank.
02What Bach size is the 48D closest to?
The Bach 6-1/2AL rim, with a deeper cup than the standard 6-1/2AL.
03How is the 48D different from the 48?
Same rim. The D has the deeper cup, which trades some high-register ease for a darker sound and stronger low register.
04Is this a step up from a stock student mouthpiece?
On a small-bore horn, yes, if you want a warmer sound with more low end. The rim matches the common 6-1/2AL, so the change is mostly in the cup.
