The guitars I have are set up with a Fishman Classic set; a Fishman Modern set; JB/59-A4; Distortion/Jazz-RCUOA5; and Black Winter/Sentient-A2.
I honestly don't care for the neck pickups on either Fishman set, and in fact I'll probably switch from the Classics to something passive (probably another JB/59 set.)
My problem is I like to chase tones from bands I try to play, and that's why the Classic set has fallen out of favor, for me. The JB bridge does Alice In Chains better, and the Distortion does Tool better, plus they can both cover a lot more ground if needed. (Actually, the Classics in drop-D do come very close for Tool, but the Distortion is spot-on. So why "settle"?)
But for the three passive neck pickups I'm using, I'd have to rank them as:
1. Jazz with rough-cast un-oriented A5 magnet
2. Sentient with A2 magnet
3. 59 with A4 magnet
Honestly the Sentient is almost a tie with the Jazz, and I think it's actually more versatile. So you might look into that one.
It sounds good clean, slight adjustments on the guitar's tone and volume knobs are quite effective, and I'd say it handles high gain better than the other two. Plus it sounds decent when coil split, too. I swapped out the Sentient's A5 mag early on, so all I can remember about it in stock form is that I didn't exactly care for it. And while the Jazz with high gain can sound a bit piercing on the higher notes of the unwound strings, the Sentient isn't as prone to that.
I can't compare the Jazz in that way because I didn't bother to install a coil-split pot for it; I've tried a standard Jazz in the past with a coil-split and it was just too thin for me. I guess I'm also not a fan of A5 magnets, (other than the JB.) I also have tried an A2 magnet in the Jazz and still didn't care for it, so as a last-ditch effort I threw in the RCUOA5 that I had laying around, and that turned out to be the right recipe. I really didn't think that the RCUOA5 would bring much difference compared to the standard A5, but it worked out well. I like its sound under high gain better than the Sentient and way better than the 59. It was a tough comparison overall between the Sentient and the Jazz, but I do like the Jazz best.
I think the 59-A4 sounds quite good clean, but still kind of boomy under gain. If I were to only play clean tones the 59 might be my favorite.
The Jazz and Sentient are both in swamp ash guitars with maple caps and ebony fretboards, so they're a little bright, the Jazz more so. But like I said, a slight adjustment of the guitar's tone knob (or an EQ pedal) fixes that issue.
So the Sentient and Jazz (with mag swaps) might be worth looking into. Good luck in your quest!
