The K-Stack is designed to be placed on the snare drum or mounted to provide a high pitch stack/hi-hat sound. It features a wooden base w/ a track that hugs the rim of a 10”-16” drum with a metal or thin wood hoop, a rubber bottom to prevent the base from sliding, holes underneath that allow them to be mounted via a wood block mount (sold seperately), and wingnuts so you can adjust the sustain.
