I recently switched back to a Jody Jazz Classic bari sax moutpiece i haven't played in awhile, and i found it almost impossible to play on my new sax. With the s80 c*Selmer mouthpiece i was using i could get great projection, and range all the way up and down the horn, and could sustain for a long time. Now using the jody jazz mouthpiece, i have found a lot of trouble getting almost any sound, can't sustain any note lower than a g at all, and can play above a mezzo forte, and thats blowing my brains out. I'm playing on a vito vsp bari horn, and using a vandoren classic 4 reed. any help would be hugely appreciated
