CONN Curved Sop/what a MPC?

Every Conn curved I have played made in the New Wonder series has had a desire to gurggle form low C down. This is common with some horns and not others. Many people just put something in the bow to help. I tried different mouthpieces and some will stop this problem. I have found that a large chamber helps but the important thing is to find one with the scooped out inner sidewalls of the rails. I had a Chu and the only mouthpiece that worked was a Florida HR Slant. The bad part is that one of those will cost as much as the horn! Look for almost anything vintage. I have one that works well and has no name, only MO on the side.

I buy a lot of horns and one of the sopranos that came in last week had a Yamaha 5C with it. I tried it and was really surprised how well it worked on the vintage Kings and Martins. Might be worth a try.
