BerpBuzz Extension and Resistance Piece for Large Shank Trombone / Euphonium Trombone Large Shank
1/3
Independent shopping perspective
The Korena take
A buzzing aid that mounts on the horn so you can practice mouthpiece buzzing in playing position. For large-shank trombone and euphonium players.
Strong match
Who this is for
- Students working on tone and pitch centering away from the slide
- Warm-ups where the full horn would be too loud
- Teachers building a daily buzzing routine into lessons
Consider the trade-offs
When to look elsewhere
- Small-shank tenor trombone mouthpieces; the taper will not seat
- Trumpet, horn or any small-shank brass player
- Anyone expecting a tone upgrade; this is a practice tool
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
Buzz extension
Holds the mouthpiece off the leadpipe so you buzz with the horn up, then blow through without resetting.
Detail 03
Resistance piece
Restricts the air while you buzz, so free buzzing feels closer to playing than blowing into open space.
Detail 04
Mounts on the instrument
It lives on one horn at a time. Moving it between instruments means re-fitting the mount.
Detail 05
Under $25
Cheap enough that each player in a section can own one rather than passing a single unit around.
Final check
Know before you order
- 01Uses your own mouthpiece; none is included
- 02Confirm your mouthpiece is large shank, not small shank, before ordering
- 03Setting the mount position on the leadpipe takes a few minutes
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit my small-shank trombone mouthpiece?
No. It is built around the large-shank taper used on bass trombone, large-bore tenor and euphonium mouthpieces. A small-shank piece will not seat properly.
02Does a mouthpiece come with it?
No. You use the mouthpiece you already play.
03Can I use it on euphonium?
Yes, as long as your euphonium mouthpiece is a large shank.
04What does the resistance part actually do?
It narrows the air path while you buzz. Free buzzing is wide open and lets you cheat; the added resistance makes the effort closer to playing the horn.
