I use the alto mouthpiece on my YAS-280 with a Rovner ligature. (I also use a 6* on my Trevor James 'Horn Revolution' tenor sax). These ebonite mouthpieces are very well made, are good all-rounders and facilitate a lovely tone. They also enable the low Bb, B, C notes to be blown by early grade players. Otto Link was recommended to me by my sax teacher. I've found no faults with Otto Link mouthpieces. Everything about them is very good.
