Does anyone have any advise on an allergy to mouthpieces? We have a keen young lad in the training band who, after only playing for a few minutes is sporting a big red sore ring on his chops. He currently has a DW gold mouthpiece, but has also tried the silver. I've tried again with enquiries to Kelly but they won't be producing a horn mouthpiece for some months to come. Its "on the drawing board". So, any suggestions please, we don't want to lose this little lad, he's a bright kid and is gonna be a cracking little player.
