The filling of the Rohema Twin Shaker Low consists of coarse steel sand. This gives the shaker the darkest sound color of all three Twin Shaker models. We use natural beech wood for the Twin Shaker and walnut fillings at the ends - so the dark timbre can also be recognized visually. Inside the shaker are two chambers of equal size, which are filled with the steel sand. This makes the sound louder, more concise and more controllable.
