The Xaphoons from the Signature Series are hcreated fresh from the rainforests of Maui, Hawaii, toasted over a fire to achieve their burnt finish, and personally selected by Xaphoon inventor Brian Wittman. They each boast a full two octaves with a fully chromatic scale, and each Signature Series instrument is hand-signed, individually numbered, and comes with a signed Certificate of Authenticity, along with an 8-page hand-calligraphed instruction guide. Perfect for true Xaphoon aficionados and collectors.
