Great avatar Frank! I think a lot of the vintage thing is snake oil nowadays, sure some of the early instruments were great instruments but as any dealer worth his salt will tell you whilst some are fantastic others can be total rubbish, take the fabled 59 Les Paul as an example, most are apparently fantastic examples and are rightly hugely desireable and sadly spend their lives locked in bank vaults, others were bland ordinary instruments that players owned, realised they didn't like them and sold them on, my bet would be that any 59 /60 Les Paul you see come up for sale on the open market will be one of the latter unspecial instruments!
We all acknowledge that both Gibson and Fender went through some serious build quality instruments back in the late 70's, I guess at that time it was easier for a buyer to guarentee a better instrument if they brought an older 60's instrument, not that all 70's Fenders were bad, that no doubt drove a lot of the move towards the vintage market.
I have a cracking 79 Precision that is a rarity because it weighs in at just under 9lbs and plays and sounds great, I had an exactly the same bass a couple of years ago that weighed in at 10.5 lbs and that sounded ok and played ok, two very different basses from the same year.
Now that Fender and Gibson have far better quality control (and they have to to compete with all the other manufacturers out there) the vintage desireabillity, at least on playing grounds, is somewhat diminished, I have a custom shop 62 Precision that is perfect for me, it is beautifully built, with nice light woods, it has a nitro finish (which on Fender's I prefer) but is built with over 50 years of experience behind it and to me offers the best of both worlds, the next argument comes because it is a "heavy relic" which sparks the whole "why make a relic" debate but for me it is the best that Fender are currently offering so I brought it!
