just to be clear, the GSR was made from a body that was commissioned from an earlier Guild era, but it was made in New Hartford.
It's "dangerous" saying "the GSR"... Some of the early GSRs, yes, see my comment below. But the GSR M-75 never belonged to that Donnie Wade stash of whitewood I believe. That GSR M-75 whitewood came from SPG in Korea after the Newark St. line was introduced I believe. The Newark St. line was introduced in January 2013 and the GSR M-75 in autumn of 2013! Much later than other GSRs. Why NH screwed that model up I don't know... Especially as they had all done correctly already on the AP M-75.
The origin story I recall of the GSR electrics is that Donnie Wade (FMIC/Guild) had a number of guitar bodies cut and assembled in Korea. The project was shelved. The unfinished and uncompleted ("whitewood") instruments sat in storage until NH decided to complete them and offer them as limited edition GSRs. So the body shapes and dimensions were chosen in the late 1990's. The wood was cut and assembled into bodies with necks in Korea in the 1990's. In 20xx and 201x the uncompleted instruments were completed in New Hartford which included finishing the wood, installing pickups and electronics as a minimum and may have included some "finishing" woodwork.
I believe Korea is not correct in that context. Donnie Wade run Jackson Guitars and, when it was sold to Fender, he went along with the sale to FMIC. (Well actually the story seems to be more complicated. Akai Electric purchased select assets of IMC, including Jackson/Charvel guitars and was sold to FMIC later on.) Wade was based in Japan at that time I think and worked with factories in Japan, so highly unlikely that Korea had a hand in them. I even think to remember that the GSR Starfire VI bodies were sent from NH back to a factory in Japan (Terade) to put the spruce top on them as NH didn't have the fixtures for that Gibson 335 type body size.
What I believe to remember is that the Donnie Wade bodies were used on the GSR Starfire I Bass, the GSR Starfire II Bass, the GSR Starfire VI and the GSR T-500.
I don't know about the GSR X-180, GSR X-150D, GSR X-500D, GSR M-85 II Bass and the GSR M-75 whitewood bodies, I think some or all came from elsewere, not from Donnie Wade.
I know that is all a lot of speculation...
