Got to wondering this today, while playing (poorly) guitar. Assuming the string spacing was narrow enough that the strings all sat over the pickup, would a guitar pickup work serviceably as a bass pickup? Like, old Steinbergers had pickups that fit in a humbucker ring, (currently EMG's HB, Rio Grande's Pitbull), but would a guitar pickup itself work? Are the differences in magnets and winding too disparate, or is it largely a matter of string spacing? Just wondering if anyone could weigh in on the subject.
