Hmmmm. I'm making a list of ridiculous things I'd like to try doing and the idea came up about using a very thin slab of either marble or granite as fretboard material. I was thinking of taking a maple fretboard, or equivalent, and cutting so it's 1/2 the thickness and replacing the removed half with a slab of marble or granite. I've been checking around and there's a marble/granite place nearby where they can do the necessary cutting. They're not certain if they can do the radiusing, but they might be able to if I go ahead and place the order. I'm wondering, has anyone tried this before? Know any problems? Is this a really goofy idea? I don't mind if it doesn't work all that well as long as it doesn't end up being something that I had wished I'd done. *shrug* what can I say? I'm just thinking of how a white/silver marble fretboard would look with a bubinga body. Thanks in advance!
