Can anyone help? I have searched the web hither and thither trying to find a yamaha xeno cornet mouthpiece (the Dave King one) to no avail! Does anyone know if they are available to buy seperately from the instrument? I have a xeno cornet and i am currently playing on a McCann but i am having problems with the insrument kicking back at me (i have tried 3 different xeno cornets. All the same!). I have never had this problem before so i'm gonna try to remedy the problem starting with my mouthpiece. I just need to find a Dave King one.
