I've had Bart's and EMG's (both HZs and CS/DCs) and the Quarter Pounders in my Jazz are still my favorite. Really high output, and strong bass and mids. As with a jazz, I roll the treble back, but not lacking in tone at all.
I like the EMG CS/DCs I have in my ESP, but they are much rounder and don't have any where the grind of the Duncans. I think overall I just like single coils in bass for mid focus and grind.
