I've borrowed a friend's Callet Symphonique, an earlier manifestation of Jerome's Jazz. I have a hard time thinking this is a large bore horn, it's so stuffy! I've tried 3 JC mouthpieces, no avail. I wrote Jerome and he called me! (an honor!) He said he saw no reason the horn should not be stuffy, i just needed to play through the horn instead of at the mouthpiece. I've tried all this and still find it harder to play than the Wild Thing I demo'ed through this site, a Chicago Benge and another friend's Bach LB 72. Any thoughts? I would think that I should be able to get a more consistant, sound from this horn but can't. I was thinking of buying this horn but am glad I tried one before I did, especially since they cost as much as a WT, which I just loved!
