The least successful mouthpiece purchase I have ever made.
It's actually not the least expensive mouthpiece that I have ever bought, as I dud but a Bari alto that was less than half the price of this one. I have also bought more than one Yamaha "student" level mouthpiece (which were narrower tips) that have worked well.
So, I was not expecting miracles from it, nor was I expecting it to sound as good as the more expensive Vandoren, Meyer and hand made RPC mouthpieces I have used.
But, I was expecting more than what I actually got. This mouthpiece, considering it was a comparatively wide tip opening, has a thin and weak sound that is almost to quiet to hear well.
The sound regularly breaks up on notes that are not especially difficult to play, such as first octave G and A and altissimo above high F# is impossible - although I frequently have no problems getting to G, G# and A with other mouthpieces and the same reeds that I used for this one.
I find the product information confusing to say the least, as I do not agree that it has "Powerful volume and rich tone tonal variations", nor is it (in my view) excellent for experienced players".
I have considered the possibility that I got a bad copy, as this is so completely different from what I was expecting. It is also quite different - in a bad way - from a 5C of the same make and material (that I dropped and was hoping to replace this with), which I found excellent.
