I've seen people complain about a lot of things. I'm curious about those complaints but I have none myself. Plus pickups are pretty easy to upgrade. I'm more concerned about setup and playability out of the box.
I bought a Schecter J-4 new and when it arrived the "hum-cancelling" Js hummed, even with both pickups on. Assuming it was a grounding problem I opened it up, didn't see anything loose… So I took out the pick ups and found the worst soldering job I've ever seen on a factory bass. There was a strand of wire coming out one of the leads, and because of a coil tap function, each pick up had three wires. All three looks like the kind of bass you would take in for a repair job. Within a couple of hours of owning it the neck pick up stopped working.…
I will say that when it was working it felt amazing and it sounded great. So, check your bases they're really great, when they work. If you're close with a good loot here or skilled at doing the work yourself I highly recommend a J4
