"Now to answer the question about what is actually different about the wood itself. The only info I can give you from personal experience comes from Edwin Wilson himself who runs the Custom Shop and truly cares more about the historic LPs than just about anyone else over at Gibby. What he told me when he gave me a tour of the custom shop a few years back was this... When showing me the mahogany blanks that were divided up in stacks by weight, he pointed out to me the lime streaking in some of the wood. He explained that back when wood was cut in the 50s it came from very old slow growth trees that were inland in the fields. And that the wood that was cut was very old to start with. He said all that wood is gone, never to be seen again, and that the current mahogany they get, while still in some cases still being Honduran, comes from different locations, mostly near the water and that the mineral content was different. He said that even the lightest wood they had would not sound the same tonewise as the mahogany used fifty years ago. Now this is a guy in the custom shop that could have told me the opposite if he wanted to, but he was being honest about the differences... Here is another observation, again Im not an expert, but its something worth pointing out. Did you ever look at the color of the back of a new historic goldtop? Why is it so much lighter than the old ones? Some of them almost look like a Korina color. And its not the aging of lacquer. If I chip off the lacquer on my original '53 goldtop, the color of the mahogany underneath is much darker than the stuff they use now. I dont know what that proves, if anything, but there is a difference in the look too..."
