I play the clarinet. I have been for quite some time now. I currently own a Buffet R13. I read about two years ago about a change that can be done to help make the middle B-flat sound less airy. Also, I got the feeling that there are a few clarinet people that are trusted to make this change. Was wondering if anyone knows about these procedure and good people to send my clarinet too.
I would go to your local music shop and ask them - generally they will be honest enough to know that the kind of fixes you're looking for are much beyond them, and if they're nice people they'll ask their counterparts about someone who knows how to do it right.
If it was me, I wouldn't take it to a music SHOP locally (maybe that's just from my bad experiences with local music shops near me, my reckoning though is they're never going to do the best job, they're just going to try to get as much money from you as possible) I would go for an instrument specialist. Someone who deals in instruments as a technician purley for the love of the instrument. They are around to be found if you look!
SimonWSTS is right... I am just lucky and the one shop around me has a bunch of people working there who truly do love the instruments. Its just the manager that you have to watch (he's always trying to sell you something).
i used to play the buffet in my school band.
amazing sound it creates, much better than some of the other clarinets i've played.
i think you could find out about local bands in your area, i'm sure they would be kind to music enthusiasts. good luck!
