Thanks for your answer.
I’ve got a Yamaha YTS-32 in combination with a Selmer C** mouthpiece and Vandoren Classic Blue Reeds 3.
For my new tryings im playing with an Otto Link Super Tone Master 7* Mouthpiece with Rico Royal 3 Reeds. The difference is enormous and so it’s a bit hard to get used to it.
I will start with those lessons and i’m very excited about it. Perhaps i should get used to the growling first, to improvise properly?
