Detail 01
Small shank

YamahaStandard Series Small Shank Trombone Mouthpiece in Silver SL45C2
Independent shopping perspective
The Korena take
A small shank tenor trombone mouthpiece equivalent to a Bach 12C, in silver plate. For small-bore horns and players on a compact rim.
Strong match
Who this is for
- Small-bore tenor trombones with a small shank receiver
- Students replacing a lost or worn stock mouthpiece
- Commercial and lead playing where a compact rim helps range
Consider the trade-offs
When to look elsewhere
- Large-bore tenor or bass trombone, wrong shank size
- Players needing a wide rim for orchestral low register
- Anyone whose lips react to silver plating
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
Bach 12C equivalent
A known reference size. If a 12C works for you, this feels familiar without relearning your embouchure.
Detail 03
45-series sizing
In this line the 45 numbers are the small-rim pieces, the 48 and 51 numbers step up toward orchestral sizes.
Detail 04
C2 cup
The 45A in the same series is much shallower. C2 gives you more body and low-end than that without going orchestral-deep.
Detail 05
Silver plating
Standard finish. Grippier than gold under the lip and cheap to replace, but it irritates some players over long sessions.
Final check
Know before you order
- 01Measure your receiver. Small shank will not seal on a large-bore trombone
- 02Mouthpiece only. No pouch, brush, or case included
- 03Silver tarnishes, so wipe it down after playing to keep the rim clean
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if it takes a small shank, which usually means a small-bore tenor. Large-bore tenor and bass trombones need a large shank and this will not seat.
02Is this the same as a Bach 12C?
Yamaha lists the 45C2 as the 12C equivalent. Expect the same general rim and cup size, with Yamaha's own rim contour and finish.
03Is it big enough for orchestral playing?
It is on the small side of the line. For a fuller orchestral low register, the 48 and 51 sizes in this series are the ones to look at.
04Will a new mouthpiece improve my sound?
It changes comfort, response, and how the extremes of your range feel. It will not fix air support or embouchure problems on its own.
