I think the same question was posed last week...
I also am not sure if they are f-spaced pickups. The may not be because of the whole metric/imperial thang.
However, they are supposed based directly on Seymour Duncan HB 103's or whatever they are, just made with cheaper materials and cheaper labour.
Whip of a measuring tape, measure them, then to to the music store and measure a 'bucker in a Fender HSS strat. Should tell you 😉
