Vandoren5JB Jazz Bb Clarinet Mouthpiece Profile 88
Independent shopping perspective
The Korena take
A hard rubber Bb clarinet mouthpiece with a very open 1.47mm tip and long facing. Built for jazz and amplified playing, not orchestral work.
Strong match
Who this is for
- Jazz and blues players wanting bend, growl, and volume
- Doublers coming from sax who want a looser, freer feel
- Loud stage settings where a classical setup gets buried
Consider the trade-offs
When to look elsewhere
- Orchestral and concert band players — too open and too bright
- Beginners; the open tip needs air support and embouchure control
- Anyone committed to hard reeds like strength 4 and up
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
Long facing
The reed vibrates over a longer stretch. Response is looser and more flexible; articulation takes more control.
Detail 03
Hard rubber
Standard mouthpiece material. Darker and warmer than metal, and it dulls if left in sunlight or hot cars.
Detail 04
Ligature not included
You need to supply one. Budget another purchase and make sure it fits a hard rubber clarinet blank.
Detail 05
Jazz profile
Designed for a bright, projecting sound with a wide dynamic range rather than a blended orchestral tone.
Detail 06
Bb clarinet fit
Fits Bb soprano clarinet barrels only. Not for A, bass, or Eb instruments.
Final check
Know before you order
- 01No ligature and no cap — you will need both
- 02Drop to softer reeds, roughly 2 to 2.5, with a tip this open
- 03Expect a real adjustment period; intonation moves more than on a close mouthpiece
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01What reed strength should I use with this?
Go softer than your usual. With a 1.47mm tip, most players land around 2 to 2.5. Harder reeds make it stiff and hard to control.
02Can I use this in concert band?
It will stand out in the wrong way. This is a jazz profile built to project and bend pitch; a closer classical mouthpiece blends better.
03Does a ligature come with it?
No. Buy a ligature sized for a hard rubber Bb clarinet mouthpiece separately.
04Is this good for a beginner?
No. The open tip and long facing demand steady air and embouchure control. Start on a closer mouthpiece and move here later.
