Please excuse me for being such a "Market Research" geek ! (its an occupational habit) I did a quick Google search, and sure enough, its a question been asked many times before.
And there is a clear reason for the confusion. See, in the "Tribute Series", not all the guitars have MFD pickups. Some have Alnico 5 or typical single coil pickups. It would make sense, that these could be locally sourced in Asia. And it don't mean they are bad ! As the Tele pickups (probably Chinese made ) in my Harley Benton TE 52 .. kick plenty booty !
Sound as "Tele" as they wanna sound ...
But the MFD ? Here is the inquiry as done on "The Gear Forum"
Still a shot out to G&L Fullerton might refresh things (I believe I did that once , but its lost in a million e-mails)
There was also confusion because G&L had some models that were exclusive to Musician's Friend/Guitar Center that were named as "Tribute" models but mostly had the Asian-made pickups. As of earlier this year the marketing folk at G&L and MF/GC have given their exclusive models the series name "Placentia" named after a city in Orange County near Fullerton - but cue up the obligatory "placenta" jokes with that name. Regardless the only source for info on these models is MF/GC.
So it depends - even some of the Tribute models will have USA alnico pickups (I think the "regular" Tribute Legacy models have USA pickups) but these exclusives for MF/GC typically have the Asian-sourced pickups. Even that can vary by model.
I hear you about "Market Research geek" being an occupational hazard regarding ferreting out details as I've been in that industry for decades now.
