Back and sides were Putamujo Arariba, which is a very rare South American hardwood. The soundboard was flamed Englemann Spruce, and had inlays of a broaching Humpback Whale and Dolphins on the lower bout. The fretboard was Ebony, the bridge and headplate were Ebony, and the headplate had inlays of my "Maui Girl"â¢ trademark and "JAD" logo. The neck and peghead were Mahogany -- not as thin as a hardwood neck, but thin and flat by classical-guitar standards -- and it was fitted with Gotoh Abalone-inlaid Gold-plated tuning machines with Shell buttons. The peghead used my proprietary Rear String Slot design and the heel has my signature Abalone heelcap.
