I have two PJs. An American Performer Precision and an Aerodyne for which I've swapped out the OG pups and replaced them with EMG GZRs.
First off, the Performer. This is my #1 bass. It plays superbly, the weight is very reasonable and with the neck pup on full and the J about half, it's got a great blend of warm and growl just beneath the surface. With both on full, you can get a bit of a MusicMan-ish vibe. Obviously not the same, but a great aggressive sound with a nice EQ that cuts through the mix, with my band (classic hard rock/heavy metal), anyway. I use Elixirs on the Performer.
For the Aerodyne, this bass is a pure pleasure to play because of its light weight. The neck is fast, BUT I found that the original pups were a bit thin sounding, which is why I swapped them for the GZRs and they have so much attack now! I use tapewound strings on this bass (not at the time of this pic, though), but even with those, the sound is lively and if you want a bit more warmth/oomph, simply dial back on the J a bit.
I'm a big fan of the P/J configuration because you do get versatility. The tone pot on these basses doesn't do a whole heck of a lot, but by changing the pup blend, you can get a nice variety of tones.
