Ok, this is probably dancing close to some similar topics in recent times but advice appreciated on this one. Guy I know who plays Bb cornet on a VB 1 1/4 C has just taken up soprano, and feels the mouthpiece is not up to the job. He has commitments elsewhere which means he cannot move totally to sop, so what do the doublers out there do? Do you have one mouthpiece that's a compromise, 2 different mouthpieces etc.....? Any thoughts on what to do in this case?
