Independent shopping perspective
The Korena take
Large-shank trombone mouthpiece with a wide rim and deep cup. For bass trombone and large-bore tenor players who need low-register support.
Strong match
Who this is for
- Bass trombonists needing depth for pedal tones and low parts
- Large-bore tenor horns with a large-shank receiver
- Section players covering the bottom of a brass ensemble
Consider the trade-offs
When to look elsewhere
- Small-shank tenor trombones — the shank will not seat
- Lead players who want an easy upper register
- Beginners on a student horn; the cup demands air
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's number 3
Lower numbers mean wider rims. A 3 sits on the large side of the trombone range.
Detail 03
G cup
Deep cup. More low-register body and a broader, darker sound; costs you some upper-register ease.
Detail 04
Wide rim diameter
More lip vibrates inside the cup. Bigger low end, but endurance drops if you are not used to it.
Detail 05
Shank taper
The taper sets the gap to your leadpipe. A wrong shank sits too deep and dulls response.
Final check
Know before you order
- 01Check your receiver before ordering; large and small shanks are not interchangeable
- 02Mouthpiece only — no pouch, cleaning brush, or shank adapter included
- 03Expect weeks of adjustment; rim and cup changes take time to settle
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my trombone?
Only if your horn has a large-shank receiver, typical of bass trombones and large-bore tenors. Small-shank tenor trombones will not accept it.
02Is a 3G a good bass trombone mouthpiece?
It is aimed that way. The wide rim and deep G cup are built for low-register volume and pedal work, which is what bass parts ask for.
03Can I use an adapter to fit it on a small-shank horn?
An adapter will make it seat, but it changes the gap and hurts response. Buying the shank that matches your horn is the better fix.
04How do I clean it?
Warm soapy water and a mouthpiece brush, weekly. Rinse and dry fully. Skip abrasive cleaners and scouring pads, which scratch the surface.
