This is the sound of a Bicentennial, Argus would have been a 60ies Bird, but Martin didn't have it yet.

Even when he rerecorded Argus some years back, he went out of his way to use a Ric for it. Since his had been stolen long ago, he loaned one from John Wetton.
I know Martin is arch-identified with TBirds (and Hamer Explorers with TBird pups), but they are mainly his live basses, he feels comfortable on stage with them. In the studio, he says, he plays anything that sounds good, Fender Ps - gasp, shok, horror! - among them ...
