I am gathering materials to build my own carved DB. I have the maple back and sides, the neck block and a european spruce top. I am going to order a fingerboard and found that they come either beveled or round. Could you please tell me what a beveled fingerboard contour is and its application. When the bass is completed, it will be set up for 100% pizzicato in a bluegrass context. Which contour would you recommend? Thanx a million, daddy-o496(Vic).
