Unfortunately, I'm no help with this one. I do agree with Philly, though. The narrower string spacing is more practical with the extra fretboard space. String slip off is way too frequent otherwise (at least with my sloppy technique :D)
What color is the body, by the way? I've developed this fascination with vintagey looking white strats with tortoise shell pickguards, and yours is particularly nice. It also looks like the pickups are the same color as the body and that the inlays are white or mother of pearl, rather than cream. Is that true?
