Sela Tac Tic 3in1 Percussion Tool

This attaches neatly to the side of my cajon with very tough velcro which is still going strong. In fact, it's actually a little hard to disconnect it once it is attached. As a separate shaker, I probably wouldn't bother, but the castanet sound along with the jingles is great - tighten up the adjuster to deaden the ringing and you have a terrific rimshot type sound, open it up and you have a tambourine beat. Overall, a really clever, useful piece of gear!
