Pretty much nothing that could be used for a guitar top. To get quartersawn, you’re only using a quarter chunk, so less than the radius of the log. You need logs that are at least 24” in diameter. Usually much bigger to get past the pith and the sapwood.The log diameters are interesting. Even back in 1890ish, not a lot of the logs would be useful for a dreadnaught top, much less a jumbo.
