I am building my first instrument, a cuban mahogany with maple core 36 string harp. After all my reading, I am confused. With today's technology is sitka spruce equal, better or worst than using 5 ply Aircraft birch laminate. As I understand it, the cost is about the same. The laminate is stronger and lasts a lot longer. Sound is about the same???? until the spruce ages about 10 years. By that time I figure the spruce will need some sprucing up.
Can you luthiers input your knowledge please.
