I generally like DiMarzios better than Duncans but the Full Shred neck is one pickup Duncan does very well that DiMarzio has no answer for.
If you want something bright but not thin, and tight, and articulate, it is GREAT for that. I use them in the neck positions of a ton of guitars.
I also do one more trick with them: To tighten up the bass on low notes on the low strings, I remove 3 screws from the neck side coil under the bass strings, run the rest of the poles on that coil flush with the bobbin top, and adjust the poles on the other coil until I get even string balance (generally raise high E and b, run G flush, raise D about like high E and A just a tad, run low E flush).
That makes the low strings tight almost like a single coil, and keeps the sound full on the higher strings. You can do fast picked muted runs all the way from low E and they are tight and percussive sort of like a single, while the higher notes/strings stay articulate and full sounding.
Try it, it will blow your mind.
The only DiMarzio full sized bucker that I can do that kind of thing with is the Super 2, and I remove ALL the screws from the neck side coil. Sounds like a really loud single coil.
You can do the same thing with a Humbucker from Hell that I do to the full Shred neck, but you have to remove the A5 mag, remove one keeper bar, install a ceramic mag, and even then, honestly the full shred neck does it better.
