Vivian Campbell, not in Def Leppard necessarily, but in his much heavier band Last in Line, everything he has recorded for that band on the three albums and all their live shows has been done on his original old Les Paul from the Dio days loaded with a set of zebra Seymour Duncan '59s, and his tone is glorious. The guitar is actually a Deluxe he bought as a teen, immediately painted it matte black and routed it for humbuckers. The same guitar back in the Dio days had Dimarzio X2N, (Holy Diver), and later Super D, DD, JB, and almost everything else but when they started LiL he put in a '59 set. For tone reference, the Last in Line albums were recorded through an Engl Ritchie Blackmore head and an older Friedman amp called a "Naked" that belongs to Jeff Pilson, who produced the albums.
