I am not 100% certain as to the vintage of this bass. In a 1995-95 era issue of "The Guitar Magazine (UK), states:
"Clayton's main bass is a mid`70's - he thinks a `76 - Fender Precision bought for him a friend during U2's early days.
Yet, he's
called it by different vintages in his last two Bass Player magazine features.
Adam referred
to it as a 1972 in the Dec 2000 Bass Player magazine.
In the Janaury
2006 issue of Bass Player, he referred to it as a 1973. "I have a ’73 Precision Bass that I’ve used since
day one. I used to think, This is the old work horse—old faithful. I loved it. I still love it, and I play it all the
time, but I try to branch out and play different instruments. I’m not so attached to any of the others."
Finish
& body-wise, this bass has had many alterations. It's had various stickers over time. Pickguards have been varying over
time from nothing to the PopMart era mirror pickguard to it's present black pickguard. It has also had a few necks over time.
While having a dot inlay neck during The Joshua Tree, it had `70;s style black, big block inlays during the Vertigo 2005-2006
tour.
