Have we ever established, for those of us not in the know, just exactly what an "LL" is? Are the "L"'s initials we're excepted to recognize? Is it a model designation for some well-known brand?

Please pardon my ignorance. I haven't shopped for guitars since I got my D-18 (that's a Martin) in 1969. For years, I've been completely unaware of the various newer premium brands that have emerged. Since I started checking into Mudcat a couple of years ago, I've come to realize that quite a few brand names which had meant nothing to me are apparently very excellent (and expensive!) guitars.
