standard-spaced. When we released our first humbuckers with wider spacing, Floyd Rose bridges were very popular.
Floyd string-spacing is the same as Fender spacing, so we naturally called the new pickups
F-spaced."
"Although some players believe that F-spaced pickups are only for the bridge position of tremolo bridge guitars, many guitars with fixed bridges (including post-1998 Gibson and Epiphone Les Paul, SG and semi-hollow guitars)
should have F-spaced pickups in the bridge position.
Most tremolo equipped guitars that have a nut width of 1-11/16 (43mm) or more should also use an F-spaced pickup in the neck position.
If youre replacing a bridge-position pickup and you're not sure what your string-spacing is, it's usually better to get an F-spaced model.
It is not necessary for the strings to pass exactly over the center of the polepieces for best performance, but it is wise to avoid a situation where the E strings are sitting completely outside of the outer polepieces."
F-Spacing
F-spaced pickups measure
2.01" (51 mm) center-to-center from the first polepiece to the sixth.
F-spacing refers to the wider of the two spacings. For proper string alignment and balanced output, F-spaced humbuckers should be used in the bridge position on all guitars with string spacing at the bridge of 2.1" (53 mm) or greater.
On these guitars, if the nut width is 1-11/16 (43 mm) or greater, F-spaced pickups can be used in the neck position as well.
Standard Spacing
Standard-spaced pickups measure
1.90" (48 mm).
