Hi all! After receiving my new Kanstul CCT 900 I have been having problems when accenting notes. For example, the sound goes all wobbly and too loud (sort of like when letting air out of balloon). I forget the name of the accent but its the one with the hat thing over top (if that helps !). My mouthpiece is a 5c. Is this mental? Or something to do with embrochure? Feels like my top lip vibrates too much or something. Thanks!
