Oliver-
I know they aren't "vintage", but I bought a
new American Standard P about a year ago and it's
very nice indeed. IMO, the fit and finish are easily on par with the pre CBS basses and superior to any 70's P I've had. The tone is good but not the same as vintage P's, I can't say I personally like the tone any better or worse, but it
is different.
Probably nothing a Lindy Fralin couldn't fix...
At least you would know what you're getting, no "surprises"!
