I don't know japanese, but according to the description of this Youtube clip, the Roland TR-808's handclap is not "satisfying". In it, Roland Executive Director Mr. Kikumoto, who developed the TR-808, says that he is not satisified with how the sound turned out. Appearently it sounds too light and like bamboo getting folded. I have never heard bamboo getting folded, but it must sound groovy.
