The Gibraltar Boom Cymbal Stack Assembly is equipped with a tilter. Allows 2 cymbals of any size to be placed on top of each other with a boom angle between them. Mounts on most 8mm cymbal stand tops.
This device does exactly what it's supposed to. It allows me to pretty much smother my drum set with cymbals in an ergonomic, efficient manner, opening up more possibilities around the kit without having to reach for anything.
