This snare has shotgun shells built in for vents. This drum was inspired by the sharp pop of a shotgun blast. Having ten vents on the drum shell dries up the overtones for clarity creating a one-of-a-kind sound great for concerts with that little bit of extra crack. The shell is made of centuries old lumber making it a true piece of Americana. This drum has 1/8 radius on the outside and a 45 on the inside. This drum sold before we could even put it on the market. We managed to get a quick sound file before we shipped it. We can customize this drum to any size.
