Grambo-Double Duck Calls

The Grambo-Double from J-CO CALLS has the same traditional look of the Grambo with a special sweet spot.  Aimed at controlling the ducks and finding the realistic ducky sound, we tuned this call to have that mellow sound.  If you want to be able to bring the birds in with a smooth call that doesn't require as much effort, this is the call for you.  Let J-CO CALLS help you snag your bag limit with this pristine double reed.
