Selmer Bb-Clarinet Concept

Maybe there are better clarinet mouthpieces, but as so often, the subject of mouthpieces is extremely subjective. On the one hand what you think about your own sound and on the other hand what you want to play with them.
The Concept is in my eyes (ears) the perfect universal mouthpiece, and you can produce a really first-class "classic" sound that remains very stable from pianissimo to forte.
But also in the pop/jazz area the mouthpiece fits perfectly for me.
As I said - very subjective, but certainly worth considering if you are looking for a different mouthpiece on the Boehm clarinet.
