Heh. Another crap title. Seymour Duncan MM pickups have 3/8" pole pieces. According to Bartolini, the ampiltude of a low B string's vibration can be as much as 1/4". In a doubled-string design (8-string, with octave and regular strings), an octave string can be placed anywhere from 1/8" away from its respective primary string, to maybe 1/2". Assuming I'm willing to go as close as 1/8", would it be possible to use an MM pickup for a bass like this? Would 1/8" between octave and bass strings be small enough to keep both strings vibrating in the sensing range of the pole piece, but also big enough to let the low B vibrate without interference from the octave B? Obviously, the B only vibrates 1/8" in each direction, at most, but, seemingly, that wouldn't leave any room for the octave B to vibrate. If I went any bigger than that, I would be afraid the two strings vibrating would go out of the range of the pole piece. What do you think?
