Palate Plate Diaphragms
Unlike other diaphragms, the Palate Plate call is placed forward in your mouth, right behind your upper teeth. This keeps you from gagging and also gives you more control on the latex. Just relax and use your tongue pressure for your note changes. Start off with less tongue pressure for lower notes. As you want higher notes, increase tongue pressure and air flow. The latex is stopped by the Palate Plate so you can't go any higher than the right note. On other diaphragms, if you apply too much pressure, or not enough, you lose the note you're wanting to achieve. The Palate Plate makes the latex longer lasting and easier to blow. The tone of the call is also more realistic.
