I've been considering using a notched piece of bone or plywood for a string guide on my guitars. I like to use a zero fret, so I don't need a real bone nut, just a notched piece to hold the strings at the right spots.
I was thinking I could use either a piece of the 1/8" aircraft hobby plywood I have or get some bone bridge blanks and use them.
I'm guessing the bone would look a bit nicer and maybe last a bit longer, but is it really worth the trouble? Please, let me know your thoughts. And if you have recommendations for other materials, please let me know!
