Stewart Spector told me one time the most critical thing about 2-pickup basses: the neck pickup does the heavy lifting, it's the one that defines the tone the most. The bridge pickup is for "finesse."
Couldn't have said it better myself, but that's because he's the pro and I'm just an ersatz tinkerer!
I tend to run
my P/J Jazz projekt (Fender Reggie-sig Jazz positioning…very important!
) around neck=100% and bridge=50-100%, depending on how much "grit" I want in my sound. And when I want a fuller "roar", I switch over to series-mode. Although recently, I've been taking a shine to a bridge=100% and neck=75-ish% sound, proof to me there's a much larger sonic "landscape" to explore.
I have always wanted to play a bass with these pickups to hear how the double P would sound

OTOH, DiMarzio makes a few humcancelling J pickups in various flavors. I tried a pair in a J copy and they were good, not as nice as P's, but better than stock thin noisy J's. I wish I had wires them with a parallel/series switch. So if you have a PJ, I recommend dropping a humcancelling J in and see how that grabs you.
I highly recommend a series/parallel mod! It's like having another bass hidden inside!
And speaking of hum-cancelling Jazz pickups…
Yes, because the J pup is noisy in comparison.
In retrospect, I should have just bought a plain old P-bass.
Three words for everyone's consideration…
Fender…
Super…
55's! Not only are they hum-cancelling, split-coil Jazz pups, they are a bit "beefier" than standard single-coils. It was the perfect choice for my aforementioned P/J Jazz.
Like others have touched upon previously, finding the right match between your pickups is crucial. In my case, I started my projekt with the Super 55 paired with an SD "Quarter Pounder" Precision. Unfortunately, the SD completely dominated the sound, despite the strength of the Super 55. Later, I found a much more complementary pairing with an MIJ Standard pup.
The church was a particularly noisy place. Amps would play local radio stations. The TV station across the street didn't help any.
Oh dear! That must lead to some awkward sermons!
