i just picked up a 9 year old d-18v that has never been played. it currently has a corian nut, micarta saddle, and plastic bridge pins. i would like to upgrade them, but i'm not sure what materials to use. after a little reading i'm leaning toward fossilized mammoth ivory for saddle and nut, and buffalo horn for the bridge pins. the guitar has pre-war scalloped bracing, mahogany back and sides, and sitka spruce top. i want to pick materials that will make the guitar sound it's best when used for a variety of styles. am i on the right track or should i consider something else?
