TAMA's Hat Stack is just about as simple and as compact as a cymbal stacker can get. It allows you to attach a small diameter cymbal to your hi-hat rod with just a drum key. Also, its tiny size – 25 mm (1”) diameter x 40 mm (1.5”) height – doesn’t interfere with your setup and is super easy to carry. It is a groundbreaking new item that can expand your sound without having to purchase additional clamps.
