The Slit Marimba Snare Drums
  This World Percussion instrument - The Slit Marimba Snare measures about 16" in diameter, 5"deep and has 15 different pitches or tones. There are many other tones other than the obvious ones . There is a conventional snare head on the bottom with a snare. The conventional head helps to amplify the sound of the wood tongues as well as contributing to the beautiful low end pitch. When the snare is turned on, it's a whole new thing. Patent pending . If the drum you like  is sold or NFS (not for sale ) in the photos just send an email so I can custom make one for you.
