Well... My main axe is an ltd M1000 from 2005, so it has a proper neck through and OFR vs the newer versions. I recently put some Ceramic Nailbombs in it and it is a metal machine sent from Heaven!... or Hell if im playing slayer... And that goes into an eleven rack for fx and then into a peavey JSX head and cab. Im really happy with my tone from that, though I'm looking for something a little warmer, less aggressive, and fatter. I think this will come from an Alnico V magnet, but I'm torn as to which pickups I should get for my next guitar, an esp NT-II.
I like the nailbombs, and was thinking about the alnico version, which I might get later on down the road for a shred guitar of mine (an edwards KL-170, really cool guitar... google it! its like a caparison), but I want to explore the BKP line a little more, and to my ears, the Black Dog clips sound the best. They also seem extremely versatile, living in the vintage hot range, and i like the cleans. Mostly im looking for something that has a really nice rhythm sound, as this guitar will be my recording and session guitar. I do session work on the side sometimes, and will be playing anything form church hymns to downtuned black metal on it (the esp NT-II).
Writing this reply has made me realize that I have a high output monster in the ceramic Nailbombs already, so maybe the Black Dogs would be the best after all.
