The Meinl Spin Spark Shaker is equipped with a screw-mounted disc that adjusts and amplifies the characteristics of the fundamental pitch. When the disc is tight, the pitch is highest; and it deepens as the disc is loosened. There is a distinctively pleasant supplemental timbre. The shaker may be manipulated in the hand for many filtering effects.Size: medium Shaker material: coated steel Pellets material: coated steel Finish: black nickel
