So the ceramic nailbomb is in and I can certainly tell the difference.
The top end zing is there with single note lines and octaves, even chords have a trebleyness to them now. The low end is back and there is a nice grunt and bark to it, powerchords sound nice and big, clear and defined. Still a pretty tight pickup, I think the Aftermath was a bit too middy and washy, and didn't go with my guitar properly. The sustain is very good too and I have that 'pissed off' type tone!
