Our 19-Note Double Sided Satori Drum is a little more complicated of an instrument but it is still very easy to play and is great for starters and advanced players. You are able to pick 2 different scales but usually you will only play one side at a time. It features our magnet tuning system making this drum compatible with A=440 or A=432hz and is always fine tunable! Each drum comes with a set of mallets that match the color of the drum. All of my drums have been powder coated by me inside and out making it 100% waterproof! Thats right! Play it in the hot springs or the bath tub!!! This instrument is made from a recycled propane tank making it virtually indestructible. It should last your children’s grandchildren’s lifetime!
