So, my pickups showed up today. I dig'em. They kinda got a solid modern tone. Like, a "studio tone" if you would. Slightly scooped. But, not dull and honky like other noiseless jazz pickups. Where they sound more like splits or humbuckers. And, they are very responsive. Fender done did pretty good with these guys. Check it out.
Apparently you do not need a ground. Like, at all on your bass. It won't hum any more or less than normal, and it will work perfectly fine all in all without it. Because, as it turns out, my bass didn't even have a ground connected at all. No wire ran. Whatsoever. And, it worked just fine in all aspects. Weird right? Learn something new every day.
