Jamie Ghio Sanches and Mike Braunewell are based in--of all places--Gibraltar! They have backgrounds in music and car modding which come together well when they make these completely functional guitars. Sanches is responsible for carving the bodies and installing the electronic components. Then Braunewell paints them.
Their website, Sword Design, appears to be down right now. But you can view more large photos of their work at Design Boom.
