Where would the bridge Alnico5 Nailbomb would be placed? Would this one be the ticket to 80/90 Iron Maiden and Rock?
Somewhere between 'NO!' and 'not really' on this one, depending on what guitar you put it in.
I've had an A-Bomb and a Cold Sweat in my SG; the CS can do Maiden and '80s rock, the NB could not. The A-Bomb can do Accept, AC/DC, Poison Idea, and other 'raspier' guitar sounds from the '80s, and generally sounds more aggressive than any of those bands but it can do something that basically sounds like them. It can't do the smoother sounds of the '80s. At least not well, and not in my experience.
Out of the three you mention it is closest to the RY but much more bottom and low mids, and hairier.
