unless you're playing a recto or something, the holy diver sounds fairly tight, just like every BKP I've tried. The highs are round in a good way, but not muffled or dark sounding. The cold sweat worked just as awesome in that same guitar too, but the sweat is like a brighter, slightly thinner and more sizzly nailbomb
The Holydiver bridge is awesome too, but it IS darker voiced. Sometimes it's just better to choose for a balanced pickup (not too bright, not too dark) if the guitar sounds fairly bright naturally...you know what I mean? It's like some guitars are meant to sound bright and cutting and for these (if they're Les Paul Customs) I'd go for the CS set personally. Very balanced set and I like the range of tones you get from the neck pickup to the bridge pickup and vice versa. It's just awesome. The HD bridge is definately less 'cutting'/'sharp' and therefore it will sound closer to the CS neck pickup...if that's what you like.
I agree with everything
but in my guitar both sounded equally awesome
the cold sweat was better for thrash metal stuff, especially Pantera (I had a cover band), and the diver was better for almost everything else, except maybe for raw 80's hard rock and classic metal
but you can't ignore the amps also
my '73 lp custom with the nailbomb sounds pretty good through my modded '77 JMP, and I bet the diver would sound even better
the other lp with the cold sweat didn't sound as good cause it's way too bright for this amp
so you gotta keep in mind that the whole equipment counts a lot
Tim usually doesn't recommend nailbombs for old les pauls cause he says they get too dark, but mine sounds exactly the opposite
very thick and punchy, but bright and not middy enough for my tastes
I'll probably buy another Diver or a similar pup (I'm thinking of a MC Afwayu) for this one and a Diver/Sweat set for the '81 Standard I'm waiting
