Squier Jazz Bass SD vs FD pickups

Hey guys, so a little while ago I got a Squier fretless Jazz Bass (just really great). So mine has Seymour Duncan designed pickups, but when I look the same bass up on Bax Shop, Thomann and other music stores it tends to cost 70 euros more and have Fender designed pickups. So what's the big difference?

Without looking up the specs, I would say the Fender pickups are likely to be better, especially if they are the noiseless variety. The difference may not be too noticeable to some though in tone.

I don't know what tone you are going for, but I think you may like dropping in some barts.

unless either set are noiseless then I would think its just a difference in wind and maybe wire gauge/insulation and/or magnet grade, and in abss that's pretty subtle, especially if you are not running a top shelf amp that will deliver those nuances from a bass instrument like maybe an eden, ashdown or vintage portaflex or a hwatt 200/sunn 2000S

even then, changing between flat, burnished and roundwound strings in different comninations of wrap/core materials and experimenting with approaching the notes differently, mixing up fingers, thumb and pick? that makes a much bigger difference to a bass sound in the mix than pickup selection! Its not like guitar. Although going active is a big sonic change but it also changes the interaction with your amp and any effects in line before the amp input....

on an Indonesian or Chinese squire I would just stick with stock and not sweat it! concentrate on playing

Single most important tonal change a bassist can make is the preamp. It makes and breaks the pickups. With a strong enough preamp, you can make fingers sound like a pick and a pick sound like fingers.
