Atelier des Cuivres 1-1/2C Ibrahim Maalouf .1

I usually play a smaller mouthpiece (Lotus 2M) so this one is fairly challenging for me, but I really dig the warm, round tone. It requires quite a bit of strength but overall is very comfortable to play.

Edit: after a while of playing this has become my favourite mouthpiece, there's something in the tone that really inspires me (even if it's slightly too big for my lips -- I think it's worth a bit of extra effort)
