I think it would be fascinating to compare "road-worn," vintage (pre-CBS, CBS), and new Fenders (MIA, MIM, MIJ). You could stick to Fender exclusively, but I wonder what it would be like to throw in some of the Fenderesque basses as well...whether it's higher end builders like Sadowsky, Lull, Nordstrand or relic'd builders like Nash. Maybe even the "lawsuit" Ibanez basses from a couple of decades ago.
I realize this might be too much to do, but I bet it would make for an interesting read. And probably be a good time for the BP staffers as well.
I'd be curious for sure.
Peace.
