The stock PU's aren't too bad . The biggest problem with bridge PU is it's a bit harsh in the upper mids and tubby in the low end. Pretty high output though and relatively balanced across the frequency spectrum. Still, they lack mojo...
The neck PU, I'm looking at a Dimarzio Humbucker from Hell or a SD Stag Mag. I really dig singlecoil tones in the neck position; those 2 seem to be the most singlecoil-like humbuckers around.
More important to me is the bridge PU, which is where I spend 90% of my playing. I guess the tone I'm looking for is something that is strong in the low end with tight, but not too stiff palm mutes. My other guitar, which is a 7 string, has an Evo7 in the bridge. I find it really lean and tight, but lacking "umph" when I chunk down on the low strings. Sure, it's a good thing for a 7 string because it keeps the low B really clear and articulate. But I want my 6 string to have a contrasting tone to my 7. Basically, something big and fat, but obviously not muddy or loose. FWIW, my 7 string is a mahogany body w/ bolt-on maple neck and rosewood fretboard.
The SA2120 on the otherhand is a maple/walnut lam set-neck with rosewood fretboard. Mahogany body with thick flame maple cap.
Here's a list of PU's I've had my eye on:
Seymour Duncan Custom 5
Seymour Duncan Duncan Distortion
So, what you think?
I prefer the Tone Zone over all those, or if not the TZ than possibly the Duncan JB - the new ones are apparently pretty hot. The TZ seems to be a more "jack of all trades" but with the Dimarzio flavor vs the Duncan "jack of all trades"...if that makes any sense
If you DO go the Tone Zone route, I have one that I purchased and never opened and am looking to part with.
