I am thinking about having a custom bass built but I would prefer to supply the wood for the top and the finger board. - What is the typical thickness necessary for the top wood? (I'm looking at a piece that is 3/8" x 14" x 21"). - What would be the width, length and thickness for for the fingerboard? - What would be the best way to store the wood, so that it doesn't split or crack, for future use? Thank you for any assistance or suggestions.
