Back and sides are casuarina (Casuarina glauca) This tree was planted all over south Florida, and it is now considered an invasive species. It is very hard and heavy, comparable to the ebonies. This is some I cut a while back from a tree that was taken down as part of a native plant restoration area.
Top is redwood (Sequoia sempervirens)- recycled from old water tanks that used to be on the top of apartment buildings in New York City. The tanks were banded with iron bands, and with the water soaking out and evaporating it can leave a regions of black streaks. My favorite top wood for a rich round sound.
Side sound port, black bog oak binding, pink abalone pearl rosette. Neck is Spanich cedar with a radiused fingerboard, headplate and bridge are Richlite, a man made material I use in place of ebony which has become expensive and involves cutting down tropical rain forests. Richlite is very stable (much more so than ebony), pure black, and very hard.
This instrument has a deep round sound with lots of volume and sustain. I am not a player but I love to just noodle around on this because it has such a nice sound. (Click on any picture for a more detailed view.) (sold)
