I have a Deluxe J V and I made it passive with Sadowsky pickups and a Hipshot bridge and tuners...
It just may be the best bass tone I've ever had. And I also own a US Deluxe with an East preamp. The Squier gets more play.
What drove me to it was the fact that there are no FENDERS that have the aspects of this bass that are so desirable...
Ebanol board - sounds, looks and feels great, keeps the neck more resistant to weather changes.
19mm spacing - it's quite nice.
3.7" wide pickup cavities - What pickups do you want? There are tons made to fit that! Dimarzio, Nordy, Duncan, EMG, Delano, etc. It's like a blank canvas.
Rear control cavity - (though Fender has a few) Pick a preamp, it should fit, no problem.
There's more, but the fact remains... Fender doesn't make what Squier has for this kind of bass. Granted, this is one aspect of a product line that includes many basses without the features, I'm just saying why I picked mine.
