What kind of shallow silliness associates a particular brand of bass with a style of music? Pointy shred-shaped Jacksons et. al., maybe, but but Warwick? Having never paid attention to anything metal at all excpet a bit of Metallica and Ozzy, I think of Jack Bruce when I think of Warwick. And the guy who used to play for Shania Twain, and some British neo-funk kind of band (Jamaroqui maybe?).
No, basses with "bad reputations" to me would be like Gibson's long-scale EB-3, most Peavey basses. Those instrumens are good, but they have a reputation for not being good. OK, the Peavey T-40 weighed a ton and was an oversized gutiar isntead of a bass design. But the original Fury, Foundations, the great Jeff Berlin Palladium, and the Cirrus basses are very good basses. So were the RJ-4, the Dyna Bass, and the Unity Series basses.
But they ain't hip, some of them didn't look very attractive, and the "Peavey" name on them made/makes people dismiss them for reasons other than their sound, utility, quality of construction, etc.
