I must be overly tired. I couldn't read the topic right and I needed to translate
"For those who are having problems with a resistant and/or stuffy alto clarinet, try a Caravan tenor sax mpc. I modified the mouthpiece to fit the clarinet and the sound is great!"
a. I had to tell someone else today this, so I'll post here, too: while you can probably make a setup like this work, to some extent, it might have a lot of tuning problems and your tone will be different. Not necessarily good or bad, but definitely different.
2. A Caravan tenor mouthpiece is $155
. Before you potentially destroy a $155 mouthpiece, I'd recommend that folks think hard about this.
iii. Eugene, it's possible that this setup works for you based on the horn you have and the setup you're using, so this is more a, "I got this to work and I liked the results!" than, "This will work for everyone!" If it did, I'd bet that Buffet and Selmer would know about it and charge $200 a piece.
Four. Remember that $155 might buy you an alto clarinet or you might be able to find a decent mouthpiece on ebay for about that price.
