I posted this on the "other" site but the clarinet knowledge is much better here so I hope for much more interesting replies. I got a nice Leblanc and it's fun to play but a little squawky sometimes around E (r1,2,3,>1,2) (depending on the reed). I went to a Music store and tried a Yamaha 4C. It wasn't any easier and the plastic sound wasn't as warm as the HR Leblanc that came with the horn. I've been looking at the Portnoy but can't find anything about them. Their site is down or dead. He died a few years ago and I;m not sure what has happened on the manufacturing end? Also the Hite seems interesting . Here is some stuff from their site. J & D Hite Basset Horn/Alto Clarinet Mouthpiece Retail price: GBP 93.00 including UK VAT (Tax) Facings: One preferred facing: Medium length, .055" tip Often known as "the ill wind that blows no good," the alto clarinet has earned a bad reputation as sounding thin, fuzzy and weak. To improve this malady, the HITE mouthpiece has a modified channel and facing design which gives a full, golden-voiced alto tone that is truly attractive. The table is widened to accept an alto saxophone reed. Medium strength Vandoren Java cuts work well. This model is also the perfect compliment to the alto clarinet style basset horn. Any suggestions would be helpful or recommendations for other MP's. I'm sure the Grabner is great (I have one on contrabass) but I'm not really to excited about putting down big bucks for an alto clarinet mp. Notice I didn't say " What do pro alto clarinet players use"
