(Go with what you got as long as it doesn't get in your way) A bad mouthiece can really get in the way, even with lots of practice and long times. (long tones are over rated) Just don't over do the mouthpiece thing. Find one that works, then lots of playing. I agree with the above statement concerning the neck of your horn. Probably the neck that came with the sax is best.

Thank you all. I notice They are always the same guys sending their advices... I agree. I'm just husking the problems to be sure of myself ! and keep practising the way every day.

The mp and neck certainly make a big difference in sound. I recall trying the original C* that came with my Ref-36, sounded completely different than the Guardala custom I use. Yeah, that may be extreme but each sounds differently. It is good to find a setup that compliments the sound you are reaching for. That said, I agree that you can get overly focused on the gear and not enough just playing. I've been using the same MP for a long time now, not really looking for something different. On the other hand, when the Ref 36 came out I ordered one (from here) and spend quite a bit of time comparing (recording also so I could hear it back). The 36 just plain sounded better and played better for what I am reaching for. Yeah, I could have just stayed with the old VI I've had since '74, but the new one just plain worked better for me. Could anyone else tell the difference? yeah, in the bottom end- but maybe only a sax nut on the rest. Hmmm, this seems like a round about way to say both yes and no. I think it is good to keep an open mind about gear but not get too focused on it. Mark
