BachLarge Shank Trombone Mouthpiece 1-1/2G
Independent shopping perspective
The Korena take
A large shank 1-1/2G trombone mouthpiece with a wide rim and deep cup. Built for bass and large bore tenor players in symphonic settings.
Strong match
Who this is for
- Bass trombone and large bore tenor in orchestral sections
- Players who need volume and depth in the low register
- Moving up from a 5G or similar mid-size piece
Consider the trade-offs
When to look elsewhere
- Small and medium bore horns — the shank will not seat
- Commercial and lead players who live above the staff
- Students still building air support and embouchure
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
Fits large bore receivers only. Small and medium bore trombones need a different shank or an adapter.
Detail 03
G cup designation
Deep cup for a broad, dark core. Demands steady air; thin support shows up as a spread sound.
Detail 04
Compared to a 5G
The 1-1/2G is noticeably wider. Bigger sound and lower range, at the cost of upper-register endurance.
Detail 05
$85 price
Standard professional mouthpiece pricing. Players often keep both a 5G and a 1-1/2G for different repertoire.
Final check
Know before you order
- 01Confirm your horn takes large shank before ordering
- 02Mouthpiece only; no pouch, case, or brush
- 03The wide rim takes weeks to adapt to; do not switch before a performance
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Is the 1-1/2G a bass trombone mouthpiece?
It is commonly used on bass trombone and on large bore tenors for orchestral work. The wide rim and deep cup suit low-register parts and full section volume.
02What is the difference between 1-1/2G and 5G?
The 1-1/2G has a wider rim and larger overall cup. It gives more low-end power and volume; the 5G is easier to control in the upper register.
03Will this fit a student trombone?
Most student trombones are small bore and take a small shank. This large shank piece will not seat properly in them.
04Why does my high range feel harder on this?
Wider rims and deeper cups favor the low register. The upper range requires more air and embouchure strength than on a smaller mouthpiece.
