I'm Mack Hoover.   My "signature sound" is quiet, but do make louder whistles, too. That typical Hoover sound is pure and sweet, but you can request it with just a hint of chiff. If you are looking for a whistle that you can play alone or with your friends without disturbing the neighbors, you've come to the right place.

"Whitecap", is my name for a any one of my PVC or CPVC mouthpieces designed to be mated with a metal barrel of  aluminum or  brass of my making, or as a retrofit on any commercial whistle that has a lost, broken, or disappointing head.
