I'm not questioning anything regarding andy. I really like him and I think he's an excellent player with a very nice sound.
I just think the guitar could be a lot better, or if it's really the way andy does like it (which is fine) it could definitely be about 1300 dollars less.
There is just no substance to warrant that price.
Any less than a JS1000 or a JEM70V? Does a vine inlay really make that much of a difference to you? Because a JEM, one could argue, is a white AT10P with a different fretboard, different-but-equivalent-quality pickups, and a different-but-still-gotoh-made bridge. And the Jem70V premium is a $1400 guitar - to you, that's money well spent. but a $1300 AT10P isn't?
I don't think a "flashy" SHOULD be more expensive than an "understated" one. The better guitar should be more expensive, end of story.
And, for me, the fact Andy's tone is TO ME way more musical than Vai's is a pretty big difference.
EDIT - wanted to also explicitly state that I'm not trying to be antagonistic or accusatory here, but rather say more or less this: that a value preposition is going to be different for every different player, and what YOU consider to be the signs of quality in a guitar are going to differ from what others look for. Accordingly, just because you think an AT10P looks cheap doesn't mean it SHOULD be cheap, or that it's no better than a $250 GIO starter set guitar. There's a lot more that goes into it.
One of the best six strings I've ever played is this:
Not mine, alas. Visually, nothing to it - oil finished alder body, matte-finished natural maple neck, two pickups, and a trem. But man, what an ass-kicker of a guitar, and does it ever sound and play spectacularly
