Subject: [kl] materials for contra-bass clarinet
>Scott Stevens asked for tips on his Leblanc BBb contra.
I would like to add that I have gone to the LaVoz med. soft bari sax
reed for my EEb contra fitted with a Selmer C MPc. This reed is about 1mm
wider than the VanDoren reed and seals nicely on the contra MPc.
>I have a "paperclip" Leblanc BBb (to low C) and spent a lot of time
>it to play reliably.
>The most important thing to do is get the pads properly seated and the
>register vent mechanism working properly. Most of the pads are held in
>screws and small resonators, and, like flute pads, the seating is done by
>inserting semi-circular paper shims. It's really a job for a saxophone
>specialist, or perhaps a flute specialist, who is used to working with this
>design. Clark Fobes told me that when he used to overhaul these beasts,
>would remove the screw posts and float in kid pads on shellac, in the
>standard clarinet/bass clarinet style. The register vent mechanism is
>insanely complicated, since it opens three holes -- a special hole for
>Bb as well as the standard low- and high-clarion holes.
>The older instruments often have a lot of slop in the action. They're a
>problem to get adjusted right, but some free play is tolerable on the
>notes of the low C model, since you don't use them often.
>If you have the "paperclip" model and don't need the low notes, you can
>sometimes improve the response by removing the final piece (for low Db and
>low C), and putting the bell on the end of the next joint, or by leaving
>the bell completely. However, taking off that piece and putting it back on
>always creates the risk of flexing the ascending pieces and throwing the
>adjustment out. I therefore leave mine on.
>Handle the instrument very gently. I always pick it up using the two

>When you assemble the instrument, always put the mouthpiece into the neck

>reed and mouthpiece. The bending back and forth of the instrument if you

>Leblanc originally made a wide mouthpiece, which takes Vandoren contrabass
>reeds. About 20 years ago, they went to a narrower one, the same width as
>the Eb contra-alto. Vandoren doesn't make reeds for these, but their bass
>sax reeds fit fine and are much better than the brown-box/orange-box Ricos.
>Count yourself lucky if you have the old mouthpiece, which works better in
>the low register.
>Mouthpieces are a problem. Old contras have often been played by "etc."

>to someone like Everett Matson, who can make remarkable improvements. It's
>also worth trying a new one. The Selmer C* is a good, intermediate design.
>However, I got one recently, and it was *way* lopsided and took my

>equipment has gotten worn, and they sell so few it's not worth it to them
>go to the expense of fixing it. However, rubber is good, and it's worth

>Even if you don't normally play double lip, you almost have to use it on

>As others have noted, Leblanc quality control is not good, and they have no
