Tycoon Percussion"s Siam Oak Cajon Congas are constructed of hand selected Siam Oak Wood, while the top "head" is made from Bubinga wood. Solid striking surface yields deep bass tones and sharp high slaps, the perfect balance between a cajon and a conga. Each conga cajon is individually handmade and tested to ensure superior sound quality. 28" tall and available in three sizes; 10.5", 12", 13.5". Tycoon Percussion uses only plantation farmed Siam Oak wood in the production of their instruments, allowing for the highest quality product to be manufactured and distributed, as well as preserving old-growth forests in our world"s ever changing environment.
