Clark W FobesSan Francisco BBb Contrabass Clarinet Mouthpiece
Independent shopping perspective
The Korena take
Mouthpiece for the BBb contrabass clarinet, the largest of the clarinet family. A specialist purchase for players who own or play that horn.
Strong match
Who this is for
- BBb contrabass players in a clarinet choir or wind ensemble low section
- Schools replacing a worn or missing contrabass mouthpiece
- Low-reed doublers who need a dedicated contrabass setup
Consider the trade-offs
When to look elsewhere
- EEb contra-alto clarinet — a different horn, different mouthpiece
- Bass clarinet players, who need a bass piece instead
- Anyone shopping without confirming which contra they actually have
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
Takes contrabass reeds
Contrabass reeds are their own size and cost more than bass reeds. Bass reeds will not cover the table.
Detail 03
$350
The most expensive piece here by a wide margin, reflecting how few contrabass mouthpieces get made.
Detail 04
Clark W Fobes
A single-reed mouthpiece specialist, which matters most at the contra end where options are limited.
Detail 05
Mouthpiece only
It affects response and intonation on a horn where both are the usual struggle. It does not replace a neck or repad.
Final check
Know before you order
- 01Verify your horn is BBb contrabass, not EEb contra-alto, before ordering
- 02Budget separately for contrabass reeds and a ligature that fits this size
- 03Check the neck cork — a large mouthpiece exposes a loose fit fast
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Will this fit an EEb contra-alto clarinet?
No. This is for BBb contrabass. Contra-alto is a smaller, higher horn and uses its own mouthpiece size.
02How do I tell which contra I have?
Check the horn's markings or its lowest sounding pitch. BBb contrabass sounds an octave below bass clarinet; EEb contra-alto sits between them.
03Can I use bass clarinet reeds on it?
No. Contrabass reeds are larger. A bass reed will not cover the table or seal properly.
04Why does it cost more than the bass pieces?
Contrabass mouthpieces are made in far smaller numbers and use more material. The price gap is normal across the category.
