yeah, im wondering why replace the stock EQ?
it looks like a semi recent JM so it 'should' have delano pickups (as seen) and either a delano EQ (as used by both sandberg and clover) or a 'sandberg' stock which is made by the guys at glokenklang.
both of those options are seen as pretty much high end by most of the bass community, though if you cant get away with the stock EQ then yeah thats a fair enough reason
just a quick Q, is the switch the coil tap for the MM or the active/passive for the EQ? my PM 5 has the latter but on a push/pull vol pot.
congrats on the sweet sandberg though too, and dont forget to pop in to the sandberg club and get your number.
