Great question I don't know if you will get the answer you want but I can attest to this
I have a 2006 Geddy it came with the raised & beveled polls very bright sounding but not a lot of low end or mids witch bummed me out it sounded good at home but time and time again playing live it got lost in the mix it was thin and not aggressive played with my amp my sans amp name it.I've had it since last Aug.so I took my Geddy franken bass it has the pickups from the first run limited edition 1998 I believe,and a Mexican jazz body dead sounding and a neck from the last run of MIJ Geddy basses.the first run pickups are flat poles that stick up a small amount on the rear D & G string .so I swapped them pick ups last Friday.things I found
the first run has bright copper and it looked to me they had more wiring,the 2006 were blk color & less wire witch explain the thin sound. my findings are and I so happy I did this! man the difference in tone really took me,it now sounds thick & deep low,meaty mids,& highs that stand out.it sounds like it should,I put the blk wire pickups put them in my Franken Geddy it brightened it up a lot it sounded deadish with the first run pickups in it.I now have a more openness to to matching up woods and the type of pickups they do make a big difference in tone. I read as you did all the threads about the Geddy pickups are they MIJ,MIA,62 custom shop? I played it out twice yesterday and got complements on the tone & that I could be heard.witch was great! instead of my normal I couldn't hear you very well. my conclusion is fender put different pickups in the Geddy basses here and their due to availability or cost I do not no.sorry for being no help. sorry man you were asking about pickups in the MIM Geddy probably the same as the MIJ is my guess and they seemed to vary.
