That was
definitely the case on my Korean '03 Tribute ASAT and on other used Tribs I've seen at my local dealer, "a-o"

G&L went thru a number of Asian hardware makers before picking Gotoh for the tuners, and I think the repro bridges. The hardware screws and pot shafts on those Tribs are different sizes (metric) than USA parts.
I couldn't make out clearly from the BuffBro pic if the 'G&L' had anything else stamped under it on the bridge in front of the saddles.
The G&L site's current descrip says:
G&L Tribute Series sets a dramatic new standard in the popular price range by bringing unique G&L features and standardized CNC quality together in a surprisingly affordable line of guitars and basses. With genuine original equipment G&L pickups and bridges supplied by the Fender Avenue factory, Tribute Series instruments are equipped with unmistakable tone, sustain and playability that surpasses more expensive instruments.
But that doesn't neccesarily mean it's correct, since they can change specs and not update things on the site, and they've had some errors.
Personal Experience example:
When I ordered my Bluesboy in March, the site said the neck 'bucker was a G&L Alnico; Bluesboys had always had a Duncan Seth Lover SH2, one of the specs that Buffalo Bros suggested to G&L when they 'commissioned' the first ASAT Classic BB's. G&L
did replace Duncans in (I think) Invaders and other HB models back in Nov. 07. But they kept the BB true to its original top-shelf design, found the error and updated the site...
after I got mine in April. (I found out browsing the G&LDP). So I took mine apart to check under the hood, and sure enough, it's the Lover in there.
