I'd buy 10 x 10k guitars. I always wonder, how much better can a guitar be than a good guitar.
My opinion: They do get better, but it's a game of diminishing returns. A flat top that costs twice as much as my Morgan will not be twice as good. A guitar that costs twice as much again will not be four times as good. My Morgan is not twice as a good as a guitar half the price. Beyond a certain point the improvements start to cost a lot, but they are improvements.
There's also non-functional aspects to consider. Some people like cosmetically attractive guitars - nice inlays, gold-plated hardware etc. Things that do little for sound and playability.
And there's rarity. The Ibanez that sparked this thread is one of only one hundred that will be made. So it has exclusivity, rarity. Hugh Cumming has a Roy Rogers limited edition Martin coming. One of only fourteen. Even more exclusivity.
As an investment? Naw, I'd buy art or something. Guitars are made to be played till there is nothing left of them.
George Gruhn, who almost invented the vintage guitar market, produced a paper a few years ago that showed that guitars perform very well as long-term investments. At one point they were outperforming just about every savings product in the USA.
It's possible that some investors don't play. That doesn't reduce the investment.
