I didn't like the 10k lil killer all that much, it was definitely not the sound I wanted. All overdrive and no 'real' tone. Coil-tapping it produced an awful sounding pickup. I replaced it with the 6k version which fits with the neck and middle (vintage SC) pups better. and has a nicer more musical tone. I guess for some people it would be a great sound, just not for me. The good thing about GFS is that if you don't like it, you're only out $35. People do say the 10k version nails the 'hot rails' SD pickup, but I have no idea if that's true.
