Phelps Aluminum Over Glass Padauk Pot Turkey Call - Loud and Crisp! This padauk pot with an aluminum surface over a glass soundboard is sure to get a turkey's attention even if they are a long way off. The padauk strike on the aluminum surface produces high-pitched and sharp clucks, cuts, and aggressive double note yelps but is still subtle enough for quiet purrs. If you are looking for a call that is different than the rest of the pot calls, this is it!
