Tremonti or Holcomb
AYE KEED, AYE KEED!
No, seriously, I think maybe you want the lowest possible output -- like the 58/15LT or the like -- and then splittable. I don't have actual 58/15LT, I think I just have the 58/15 and 85/15, but I'm extrapolating only a little bit from my experience. I also really dig the 57/08 when they are split.
Definitely concentrate on the split sounds -- that's where you'll find your most singlecoil-like tones.
Also the 408 narrowfields. Again, split, they sound sublime, but those middle positions --neckhumbridgesplit or necksplitbridgehum -- are superb. But now I'm just talking about my own tastes, not yours.
