Fender Vintage '64 J pups vs. DiMarzio Ultra Jazz pups - first of all I gotta say that I'm well aware that a certain set of pickups are not going to sound the same way in any two Basses. Okay, with that being said, I have a set of Fender Pure Vintage 64 pickups in one bass (with an Audere JZ3 preamp), I also have another Frankenbass/Parts Bass (an SX Jazz body w/ '70's spacing) that has a set of Dimarzio Ultra Jazz pickups ( that for whatever reason rarely ever gets played). Both Basses by the way are Ash body /Maple neck. Last night while switching between Basses I realize that DAMN! these DiMarzio pickups sound freaking Amazing! They had more output (w/no preamp mind you), they were clearer sounding, had more Growl- Great growl I might add, they were warmer and had more punch. So I'm thinking, since this Bass is sort of a Spare parts Bass laying around, I'm thinking, what are the odds of these DiMarzio pickups sounding just as good in my new favorite Bass? Now I know some of you are thinking, Why don't you just leave DiMarzio pickups in that Bass and start playing that one more often? Well, because I was really considering selling that Bass because it never gets played, but now I don't want to sell it with the DiMarzio pickups in it, I'd rather sell it with the Fender pure vintage '64 pups in it (or some other pickups that I may have lying around). Well, there's no guarantee that the DiMarzios are going to sound as good in the other Bass, but I'm definitely going to try it, cuz there's only one way to find out right?
