However, I think at least some of this is to sucker newer players into thinking they're getting a pro guitar ("it has duncans! wow!"), since you can clearly see the "Seymour Duncan" written on the pickup. You can't judge the quality of the wood in the guitar just as easily as that, especially if you're a less experienced player.
ding ding ding ding ding, we have a winner!!!!
remind me to buy you a beer in london!
that is what most people think.. it has quality parts, but that doesnt mean it's a good guitar.. who knows what wood it's been made of, does it need a fret dress, or even re-crowning (low end epis and ibanez guitars especialy.. horrible horrible)
like i said, they look good on paper, but what's underneath the paint?
like the ongoing jacskon/ltd arguement.. ltd has all this name brand stuff, where jackson (only recently) got just name brand pickups.. and they're still a bit more expencive, so people go for ltd, cos they think they get more bang for the buck.. if you want real bang for the buck, buy used 80s'early 90's ibanezes, jacksons/charvels. that's where the gems are
i know for a fact that duncan tried to shift regular production models over to korea (where their duncan designed pups are being made), but cos people said they buy USA products, for the quality, cos who knows what quality the MIK will be, and that they would lose a lot of their customers, they (for now) left the production in the santa barbara facility.
for dimarzios, i wouldnt be surprised if they were already made overseas. i had a PAF pro in my hands the other day and the build was so flimsy.. it looked like it would break :P dunno.. maybe it was tinkered with, but the guy claimed it was new... but over in these parts you never know
