 The fretboards are all made from "Curupay" harvested from forests certified in accordance with the rules of the Forest Stewardship Council (FSC).The mahogany used in the construction of this model is from similarly certified forests.The SmartWood Exotic had a thinner, belly contoured, body than the Studio (somewhat similar to that of the Les Paul Custom Lite), and had "smart wood" written on the truss rod cover.
