it's big!
I bought my yamaha 300 tenor about five years ago. In terms of tone and tuning, I've been very happy with it. You do have to work a little harder to get it in tune for the higher octave, but this has been the case with all of the tenors I've played. The lack of absorbtion can be an issue too. It gets clogged up very easily.Also, do you have small hands? - it is a big instrument. If your hands are small like mine are, you will probably find yourself avoiding middle Cs, C#s, and Fs (or suffering the consequences, as I am currently... ouch). I can only play it for short amounts of time. Some others who have played it haven't any problems in that respect though. But I wouldn't reccomend it for young kids.
