well, like I said. it's pretty damn dark in an sg, but the ceramic magnet helps it to retain its bite and tightness. never gets even remotely muddy, even with the gain piled on through a non-valve amp (I've tried it through a marshall mg30 and avt50h as well as my dsl401). mine has 12 poles so it's got even more low end than a standard one - the bottom end is certainly prominent, but as I said there's still a nice snarl to it. cleans are much the same story - very deep, but with a nice sparkle on top
I actually wouldn't agree that the cs sounds more modern than the nb. I guess if you were looking at the pure stats then the fact that the cs is slightly more scooped in the mids would seem to indicate so, but my impression has always been that the cs has a nice semi-vintage vibe to it, whereas the nailbomb has always been full of raw power and aggression. the nailbomb does clean up better for me, but then again it's in a basswood guitar with a maple top as opposed to the all mahogany sg
actually starting to think I have too many guitars now. 3 out of 5 have bkp pups, and only one of those has been used in the last month. the other two are telecasters though, and I $%ing love telecasters. actually, thinking about it, the bkp-fitted one that I have used is a telecaster as well. I $%ing love telecasters.
