I think EMG makes a direct replacement set, and somebody else does (don't remember) - but most companies do not. Bummer I know - that's why I ditched my Squire.
Also. FYI, my tech, (who is pretty sharp) wasn't even aware that Jazz basses hod two different sized pick-ups, to the point that I don't think he ever believed me.
The worst part is that the original pickups in the Squire 5 custom I had were crap.
That's a strange reason to ditch a bass.
For one, you can always go with a larger rout and put in soapbar shaped pickups like the Nordie Big Singles which opens up a LOT of options for Nordstrand, Barts, & EMG's
Another way to go is to just rout it and put on a pickguard.
I'm actually quite satisfied with the stock pups in my DAJV...but I may be changing out the preamp in the not-so-distant future.
