I am a high school bari sax player in the jazz band. I am probably the only one there who actually listens to jazz all the time and wants to continue jazz beyond high school. I love the bari sax so much and really appreciate how it is supposed to be played. I listen to mulligan all the time and have started to develop his sound. I got a conn 12m to use for marching band since I needed a horn that I wouldn't bawl my eyes out about beating up but would also be good for jazz. This thing is supposed to be one of the best baris out there, but I don't like mine. It is not in particularly great condition and using it in high school is sort of hard for normal concert band since my mouthpiece doesn't like the ol conn. I have read old horns don't like modern mouthpieces. I am always sharp and in concert band it drives me nuts. In jazz band I could easily buy a vintage jazz piece and be fine, but the c star the school wants everyone to have wouldn't work on my horn. My horn is also one of the later conns 1967 exactly. It also has a pretty bad repair job done to the bow and a really ugly lacquer job. I assume it is a relacquer but it has some spots where it looks pretty screwed up like on the bow where they used a torch to get the dents out, or on the inside of the bell towards the end there is a spot peeled away. I also hate the octave key mechanism. I cant play above an a without it being fuzzy since the octave pad doesn't open all the way. It has to do with the fact that if I move the neck to my head when sitting down the octave hammer doesn't hit the receiver. Overall I respect and usually prefer vintage stuff but in this case even though I think conns are great I think it might be time for me to look at a more modern horn with better keywork etc. I think overall it would benefit me more. What are good modern horns to look at for jazz. I have looked at cannonballs which are pretty appealing to me but I also have considered a p mauriat 302 since it is a low Bb which is supposed to be better for jazz. I like the idea but is it any good? I also looked at a kielwerth sx90 having heard it is similar to the conn chu. I also looked at a Chinese taishan bari sax which had great reviews on SOTW and has some really cool lacquer options as well as double arms on the low c key. Overall I think a low a bari would benefit me having lots of low a's in my music but I don't want the drawbacks that lots of people have been talking about with low a horns and their less "fat" sound. What should I do? Thanks!
