Thanks for the links, I hadn't heard Abominable Putridity before.
To me, for bands like them and Skinless and many others, always sounded a little more organic than some, so I'm not sure I'd recommend a ceramic magnet right off. They just don't have the same pick attack that a ceramic pickup can give, from what I remember when I had my C-Pig in my guitar it had a heavier pick attack than some of these tones. So you might consider an alnico if you want that smoother immediate attack.
