I might start with saying that I'm not a very seasoned sax player and this is the very first mouthpiece I bought.
I nonetheless appreciated the improvements on the noname stock mouthpiece. The sound got a lot warmer, rounder and way less metallic, with a better perceived intonation along the whole spectrum.
I also found it a little easier to play, also with harder reeds.
It is also quite sturdy, no signs or scratches can be found after nine months of practicing.
It surely isn't a professional mouthpiece, but ideal for who, like me, still has to find his grasp over the instrument.
