It really is strange to me that every single one of these has it's own voice. I probably am the only one who can hear the difference, as they all sound like a Beansprout after all. But, I love the process of getting to know each of their voices and shipping them off to you for the real musical experience to happen. I take a pile of wood, brass and plastic, do 1000 tiny, mundane operations and out comes this unique musical tool. I'll never get sick of this. This walnut is from the Carpenter Ant stash in Portland and the pistachio is from California orchards. It is for a guy named Tom who has the important job of really getting to know this one.
