Bill, vintage guitars and amps, Silvertones, danelectros, silverface fender amps are all hold very well. as of course, Fender strats, tele's, Gibson Lp's, Martin acoustics, even some of the high end custom shop stuff is holding well.
I certainly don't mean any disrespect, but I think you're the only person I know of that feels that way! I hear stories almost daily of the nosedive in the guitar market. I know my friend Brad almost bought a '60s Strat when they dropped down from 25K to 10K, in about 2009. Thankfully he waited even longer and found one for 5K last year.
Just a quick google search brings up all kinds of sad stories:
Market speculators then started playing guitars like junk bonds or real estate, buying instruments just to flip them like Florida condos. Private equity firm Bain Capital jumped on the bandwagon by buying out Guitar Center in 2007.The onslaught of the Great Recession changed the tune. Just as the real estate bubble burst, vintage prices fell faster than a Led Zeppelin."Guitars got touted as great investments," says Gruhn. "And when you get speculators who buy strictly to flip things, they can build it into a big bubble and a frenzy."The turn was disastrous for those who had paid record prices to build rare guitar collections starting in about 2005, only to see the market plummet.
Edit: from what I can gather, you are correct that the vintage guitar market is currently "holding well". I don't agree with your earlier comment that the economy didn't affect the guitar market, it seems to be common knowledge that it tanked. But from what I'm reading, the market has since bottomed out and is holding current values, possibly even on an upswing.
