Robert Taylor talks about this on youtube. He can source Ebony from Madagascar and Cameroon. Though he says a lot more Mottled fingerboards will be the result of worldwide shortages. He also does a video on accessing storm damaged spruce trees in Alaska. I 'd heard of the possible exemption in the CITES agreement a few weeks ago-good news now it seems. What really blew me away was the thick floorboards of the Singapore Museum- all Ebony. How many colonial buildings are like that in Asia? Also furniture is not able to be made from A grade mahogany anymore. My millionaire twin brother has a dining setting of aged Mahogany that was twenty years aged, shipped to Australia and he purchased this superb setting 20-30 years ago second hand ( it's in mint condition). It's been happening since Chippendale made furniture in the 1700s. The average back and sides is 3mm ( on an acoustic)or roughly a little less than 1/8" or 0,001" in US terms. How sad must classical musicians feel also?
