So i got the pickups and installed them on my rg550. WHAT A DIFFERENCE! The breed neck is probably the best
neck pickup ever made. Every note can be heard clearly, and it has such a sweet tone. Not too dark and very smooth.
The evo2 isnt a good match for a breed neck, i have to say. When i switch pickups, it sounds like im playing a different guitar. Im happy though. Enough versatility till i get a new guitar

haha. It's bright and.. all over the place. Not that high of an output, very VERY articulate and perfect for vai/satriani stuff.
My friend left his rg2570, which is equipped with a D-Sonic and an Air Norton at my place, and i got to compare the two pickup combinations. I'll start with the
bridge pickups.
The D-Sonic is more powerful than the evo2. A lot better for metal/progressive/more "refined" or "controlled" riffing. I can't explain it any other way but the D-sonic sounds organized and the Evo2 is all over the place. Evo2 kills the D-sonic when it comes to lead/solo playing tho.
Between the Breed neck and the Air Norton, the Breed wins, IMO hands down. On my setup, the Breed sounded more petrucci-ish than the Air Norton, too. It's more powerful, more precise and has a smoother tone than the Air Norton.
As for cleans, i found the Evo2 and Breed to be more to my liking. The D-Sonic and the Air Norton have excellent cleans, but too Dream Theater-ish for me. The versatility of the Evo2-Breed Neck combo makes the cleans absolutely beautiful.
