I'm going to watch the video when I dig up $250K of discretionary money and need the info. But seriously -- those many posters who, on this as on many other threads, insist that concern for points of fact is somehow being picky, or who toss in hearsay or ignorant, misinformed notions as though they are facts, are really dragging down the usefulness of the whole forum. I'm sure the video was well-intended and mostly correct (which is about as far as anyone seems to get when talking about this subject) but it really should have included a serious disclaimer that it is a good-faith effort to introduce points of authentication but that it is essential to use several such references and never rely on only one because some of these points are always in contention and changing. It's a bit ridiculous and irresponsible to present something as though it's definitive when it cannot possibly be and obviously is not. For all those who think it's "good enough" well, when you're ready to put $250K on the table, you'll want to triangulate with some other, differing sources. You know, one of the coolest things about LPs from this era is the way that center seam drifts (being hand-placed), not that it's always true, because it isn't. That's part of the very nature of these guitars and how they were made. I'm really grateful to the people who are always working on this stuff -- including the guys making the video -- because even at this point, it's hard, perhaps impossible, to get everything right.
