Re: yanagisawa 901
A few things, you should take your horns to a good tech, and have them adjust the pad heights of the out of tune notes for you, that should help tune you up. adjusting the octave key for that is pointless, it wont do anything.
Also, it doesnt matter what sax you get, or what note you tune to, some of the notes will always be a little sharper, and some a little flatter. YOU as a player have to know what to do at those times to get your horn to come into tune. Mostly that means lipping it up or down to get it it, and sometimes there are tricks you can use(ex: if your line 4 D is sharp, add your low B key and it should tune up!)
Hope this helps you some
