I bought these for my P-bass thinking they'd be kind of midrangy/growly. Granted, I haven't given them time to brake in, and I'm transitioning from Chrome flats. But to me they actually have a kind of scooped midrange, much different than the sound I was hearing in my head. Would Rotosound Nickels be a better bet for acheiving that sort of late-'60s/early-'70s roundwound sound? Warm muted top end, but with a very present (perhaps aggressive) midrange?
