Thanks for the comparison. I also prefer white Tusq for replacements when needed. Fortunately I play mostly vintage guitars (like the 1934 Gibson "The Jumbo" in my photo) which still have the original ivory nuts and saddles in very good condition and using woods that are banned and no longer available. The guitar pictured has and Red Adirondack spruce top with mahogany back, sides and neck and a Brazilian rosewood fret-board.
I also have newer guitars, but for the kind of music I play I generally prefer the vintage pre-war Gibsons. The guitar pictured, eighty-five years old, is probably the finest guitar I've ever played, and I've played a great many guitars both old and new. It's extremely powerful, a very powerful base yet the treble separation is perfect. I'm very fortunate to be its present owner.
A luthier in the UK, Adam Gledhill, has made several guitars to the specifications, bracing-patterns, internal and external templates, etc I supplied him from my guitar and has duplicated that guitar as faithfully as possible.
Again, thanks for the comparison. And for your music. Very nice!
