The clarinet is not a saxophone, at least that's what real clarinet players tell me. With that said, I think your set-up is fine. A bigger bore clarinet might make a slight difference, but getting a more open mouthpiece will make it louder. I play a Vandoren B45 because I can't play in tune with anything else. I do, however, have a couple of old Brilharts, a #3, #5 and #7. The #7 will take the paint off the walls, but it's not a REAL clarinet sound. I'm sure the Yamaha if fine. "Pepps" plays one.
