I bought a 10m fan mouthpiece what is an acceptable range in tuning. I use clear tune and with the Morgan Fry the needle is bang on but with the 10m fan its halfway in between the 2 notes. If i back it up it gets closer to being in tune but its so far back towards the end of the cork its almost hanging of the end. Tried the kanee studio and bang on do some mouthpieces just not go with some saxes.. or do i have to work at it.. its a showtime new model and a buescher big b 1945.. I haven't tried it on the 10m yet but you'd think.. what is classed as to far out of tune for a beginner.... Thanks as always
