I hope this post doesn't get taken out of context & it's only speculative as I haven't had the oppurtunity to play one of the originals, but I have to think a custom shop 50's or 60's from either Gibson or Fender crafted by their top luthiers is probably a better instrument overrall than a production model from that era whether it be a '52 tele 54 strat or 59 lp.
It's the rarity & collectabilty of the latter that sets the financial value as well as the fact both fender & gibsons purpotedly mass produced garbage in the '70's
For example it was in the late 60's early 70's that 58-60 LP's became revered, now would a custom shop '59 reissue 10-15 years old be as good or better than what a real 59 would have been in 1969-1974?
