hey loverock
i got a 2004 quilt top and put a pair of sd 59 in it. cause i never liked the mark 2's and the guitar sounded great then i got a 1985 ls70 with sd 59 in the neck and a alnico pro at the bridge in it and hated the sound , swapped with a guy in canada for a pair of tokai p/u's dont know what ones but the sound is superb. i bought a 2002 70f couple of weeks ago with the mark2's and again the sound is awesome . tried the sds in it and it was nowhere near as good sgo put the originals back. i think that it just depends on each guitar what sounds good in one might not sound good in an identical one. just trust your ears.and enjoy your axe
