Hey Manny, 1st thing I want to say is thanks for this forum and your willingness to answer our questions. I have another Monette mouthpiece (B15LD) and was wondering how long it takes to get used to it? I have had many different size Monette's over the years but they never seem to work out for me. I was reading one of your post about the dreaded double buzz and that seems to be one of the big ones for me while playing a Monette. Is there some things I can do to make the switch a little easier? A little info on me...I started playing in junior high school and never really took it seriously (I regret now). I stopped playing for a number of years and then started back. I have been, for the past 6 years or so, a small mouthpiece player. Most of my playing is done in out church band and we play some great, and hard, music. I play mainly lead (on parts where there are a lot of high notes, 2nd on the other music). The other trumpet player is a retired Navy band player and he is a great reader and general player... just not the chops for the upper stuff. If you need any more info let me know. Thanks for your time and thoughts!
