I possde an S981 yana sax for 8 months (purchased from Feeling Paris) and the Jazz practice. J'apprcie particulirement timbre (associated with a bonito meyer mouthpiece, Vandoren V16 3 1 / 2) and cltage. I tried seven sax sopranos before you buy, the Selmer Action 2 and 3, yana S901, the Yana and bent yamaha SERIES 6 (675) and 8 (875). In my opinion, the report qualitprix is ​​unbeatable. This is well worth a sax selmer II action is lgrement infrieur III in action selmer and yamaha 875 (LX and EX) but less than 1000 euros rating. For me it is much better than the S901 yana (not bad for the price) and yamaha 675 (not great).
For the accuracy (main problem sopranos), it's really not bad, even if it is necessary to work constantly that.
The sound is quite ron and it takes advantage of two jars: jar curved for comfort, especially at home, the jar right for sound and power.
