Just wanted to thank all who looked in on me and posted comments.
I am convinced that what I have is not SD but the original pup that was in the axe.
SD APS1 RW/RP are 6.4k with cloth insulators.
What I have is 5.5k with plastic insulators.
The pups that I have in the Gibson Melodymaker are Dimarzio Fat Strats Pre B.
They are 14.3k. Unless someone can convince me otherwise, my plan is to go with them.
Would like to have old Gibsons back, but that isn't happening.
Chalk one up to experience.
