I was thinking about putting ivory bridge pins in my "new" 1998 Gibson J45 and ran accros a legal source (within the US) for Pre-Ban Elephant Ivory. http://www.ivorybuyer.com/sales/guitar_pins.php They offer (with Pre-Ban Documentation) bridge pins, nuts, saddles, and strap pins in either Elephant Ivory or Ancient Wooly Mammoth Ivory, as well as traditional Bone (Oxen Bone from the Middle East). They note the acoustic properties of the modern, Pre-Ban Elephant Ivory as superior to ancient fossilized ivory, as well as superior to that of Bone. They also offer specially treated Ancient Wooly Mammoth Ivory and say it offers a "softer" sound many guitarists seek. I never tried Ivory, but do like the sound of a bone nut and had them installed on my '31 Duolian, wood body acoustics and several electrics Can anyone comment on using the Elephant or Wooly Mammoth Ivory? How effective is this for nut, saddle, and/or bridge pins?
