New Old Stock Buffet S1 or S3 Alto Saxophone Neck. We have a acquired a few New Old Stock necks for the Buffet S1 or S3 alto sax. We've also playtested these necks on the Buffet Super Dynaction and the Buffet Senzo. When implemented on the SDA, we noticed that the intonation on the horn locked in more solidly and evenly than with the original SDA neck without noticeable change to timbre or response. When used on the Senzo, the excellent intonation remained largely unchanged but the timbre got ever so slightly brighter with more high overtones than with the solid copper Senzo neck.
