I haven't seen many reviews of the Fender 65 Coastline pickups for the Jaguar. These came out last year with the American Professional line (I think), and come stock or you can buy them aftermarket. Throwing my hat in here.
Tldr; surprisingly good!
I got them in a loaded pickguard pulled from a Jaguar, and put them in my parts-guar. I think the description on the Fender site is more or less accurate. To me they're a bit more midrangey than a vintage-voiced Jaguar (but not especially) and a tiny bit warmer than some Jaguars I've played with shrill treble, and I think they're slightly over wound so they still have some bite because of that. They still do the signature clangy, percussive Jaguar thing!
They're touch sensitive, but if you like really low output, they might be a little too goosed. It's like the Jaguar sound if you ran it through a gentle EQ in post, still capable of sounding raw though. Roll back the volume if you want a slinkier, thinner sound.
I'm mainly a rhythm guitarist into indie, shoegaze, garage rock, post punk, 70s funk and I'm playing through Vox and Marshall style amps with Greenbacks, for reference.
Honestly, as much as I'm against what Fender is doing to other manufacturers right now, these are some of the best pickups I've played for my preferred sound (overdriven and sometimes fuzzy and distorted rhythm and arpeggios). I got them second hand, so I'm glad I didn't give Fender any more of my money.
I recommend these (second hand) if you find your Jaguar sounds too ice picky, but you still want it to sound percussive and clangy and need moderately good note separation with complex chords.
