I really wasn’t sure. They are dated 1978 on the back. It had a Burstbucker alnico v when I got it. The original pickup was included with purchase. I’m glad I put it back to original.
I quadruple tracked the Crazy Train solo with my 79 Goldtop on a backing track with the original solo deleted. I love these stock pickups!!! I got the backing track from OrangeGoblin.
I had Sweetwater refret and plek my 79 Goldtop with 6150 stainless. It was about 400 dollars. It is not the same guitar, in a good way. I wouldn’t do it if you are not going to hang on to it though.
