This is the new Aizen LS 7* tenor saxophone mouthpiece. I have one of these for my alto saxophone that I love and am lucky enough to be able to try this tenor sax model. I ‘ve had it for 2 weeks and played it almost everyday. These are advertised as being copies of a vintage “Slant Signature” hard rubber Link. This mouthpiece played great for me! It had great volume when I pushed it but could get nice and lush sounding when I laid back. There is a certain graininess and character to the tone that I really loved. I compared the baffle to my other link pieces and pics I’ve seen of slants and I think it’s a pretty close match from what I’ve seen. It has a baffle that slants gradually into the back of the chamber. There are no dips or pockets in the baffle like many modern Otto Link mouthpieces have. The upper register and altissimo were a breeze with this mouthpiece and the notes were full and round. Actually, this piece reminded me a little of the Selmer Soloist mouthpiece I use to have because it had that same dark core to the sound but this piece has a bigger sound in my opinion. I have decided to send it back but only because the tip opening wasn’t quite right for me. I think I would like to try one of these in an 8 in the future.
