I have been playing my selmer sba alto ever since I came across it in 2011, and I have played on several mouthpieces over the years. Getting the entire range of the horn to resonate evenly and keeping it in tune has always seemed like a lot of work no matter mouthpiece I adjusted to. This was my first syos mouthpiece, and immediately I noticed a difference in my tone upon the first day playing on it. It definitely fit the sound characteristics that I was looking for with my sba, but it also had the flexibility to get more modern colors out of it as well. It had lots of power and just enough resistance where you can push the air and play with intensity. I was so impressed with the quality of the mouthpiece that I ordered a custom for myself. Definitely give this mouthpiece a try, especially if you're playing on a vintage horn!

I have been using this mouthpiece for two months. It feels lighter than I expected, and while I used a 7 opening with my Meyer, I’m now using an 8★ with Syos (this is just my personal experience). I pair it with a Syos 4 reed, and the response is incredibly smooth, with a tone I really love. I even used it at a large outdoor festival, and it projected beautifully through the microphone, allowing me to perform comfortably and confidently. I no longer feel the need to search for another mouthpiece. I highly recommend it to everyone.

Me ha encantado la experiencia con Syos, pedí una boquilla que cuando llegó no me satisfacía totalmente con el sonido ya que era demasiado brillante para mi, solicité el cambio por otra y todo fue perfecto, llegó en tiempo y esta que me mandaron es PERFECTA. 5 estrellas para el trato y la gestión de Syos.

I bought an alto 5* Godwin Louis mouthpiece thinking it could supplement the Smoky 5, my first Syos mouthpiece, with subtle sonic differences. It does exactly that. I use a softer reed with it, Legere 2.25 vs 2.75 with the Smoky.
I did notice that the mouthpiece’s carmine red color was bleeding onto my fingers (spit oozing out if the horn) initially but that issue seems to be going away. Paper towel photo after dabbing the horn following my initial playing session.
