It looks to be a CBS era because of the block inlays on the neck and of course the plump headstock that a CBS J Bass is known for. This was the Jazz Bass that John McVie used on every gig from 1967 up until the release of Heroes Are Hard To Find in 1974. He also played a few Tele basses around that time.
Anyone know what year this Jazz Bass was manufactured in? I would guess 68, but who really knows but John himself. I suppose he still owns it, but he switched to Alembic around 75, presumably to get a thicker tone. I have written to much of the FM members but nobody has ever written back.
But albatross has a great tone on his bass playing. If anybody has info on the Jazz Bass McVie is playing then share it here.
