I orderder these pickups as replacements for my Squier bass and they've made a huge difference.
Not only is the sound between the two pickups distinct, but they are also extremely quiet. I was a bit freaked out when I first warmed up my amp due to not hearing... anything, until I plucked my string.
There is zero noise, only the sound of your bass. I'm still wrapping my head around that.
While I'm okay at soldering, I appreciated the fact that I didn't have to do any while installing these. Just follow the guide and connect some wires!
I DID do some soldering though, but that was due to me being stubborn and not wanting to keep my battery under the control cavity. So to avoid that, I routed a battery box to the back of my bass, put the plastic holder in there and route the wires from that to my control cavity. After that, I cut the wires from the solderless battery holder that the pickups came with and soldered those ends to my battery box's wires.
If you're willing to stick your battery under the cavity, you don't have to do that though.
In any case, amazing pickups!
