Help fine-tuning my A2P humbuckers

Hello all! I've got a PRS SE Tremonti from 2014. It's a thin all-mahogany body, with a rosewood fretboard, 25" scale length and 10" fretboard radius. Think of a Les Paul Less Plus and you're most of the way there. I bought a set of Alnico II Pro humbuckers and had them installed. A covered humbucker in the neck, and uncovered zebra in the bridge because yeah, I'm a dork. Anyway. I picked it up again recently after playing other guitars for a year and a half and I'm not happy with the clean tone I'm getting from it.

I'm running through a Crate practice amp right now, but I had the same dissatisfaction with a Vox AC4C1-12 with a Celestian Blue speaker. Initially bass, mid, and treble knobs were at noon but I've been boosting treble to 1-2 pm, and dropping bass and mid down to 9-10 for more clarity. The bass is still boomy though, and there's a... quack (?) in there I don't care for as well as some shrillness on the top end.

I'm trying to get a clear warm tone from the neck, something like an A5-based vintage output Telecaster neck pickup with the tone rolled off a bit into an amp with bass/mid/treb at noon. If you've played a new Player series Telecaster recently, that'll give you an idea, just fatten it up a little. When I push the treble up though, or cut the bass/mids on my amp, the neck A2P sounds lifeless.

Should I try lowering the bass side of the humbucker and raising the pole pieces slightly?

When it comes to the bridge though, it sounds too thin without enough output. Twangier than the neck, thinner, much less bass. I'm expecting that flipping over to the bridge would give me a hotter tone, more muscle, but that's not what's happening here.

Did I goof by going for the Alnico 2 option? Should I have just gone with the Jazz neck and bridge? If I swap in an A5, will that boost clarity and output a little without getting muddy/flubby?

If it helps, take a listen to Lucille in this song and roll the treble down just a tad and that's what I'd love to be at.

IMO there is quite a contrast between the APH-1 neck and bridge. The neck tends to be a lot warmer than the bridge. Your set may be extra warm in the neck due to the metal cover, but I not sure if that is the only issue for you.

I have 2 suggestions to try:
1) Raise the bridge pickup extra close to the strings to get a fuller tone.
2) Swap an A4 or A5 magnet into the neck pickup. A4 will be about 75% similar to stock A2, just a little bit more clarity and bite. A5 will be obviously brighter and make it equivalent to a SH-2 Jazz.

I grabbed my 32nds/mm ruler and did some thorough adjusting according to various guides I found online, including Gibson specs for the A2 PAFs. Compared to most specs I came across, my humbuckers were too far away from the strings. I then balanced bass/treble angle until it was fairly to my liking, and have started tweaking individual pole pieces. It sounds a hell of a lot better than before. I knew it had to be something stupid on my end, rather than a design issue with the humbuckers.

An A5 will increase clarity and won't sound flubby. But I'd be experimenting with very small changes in pickup height before that, as there shouldn't be any shrillness or quack at all. Not being familiar with the guitar, is it 22 or 24 frets?

Hmmm. Shrill and quack . . . is there any chance it is wired in parallel instead of series?

The guitar is 22 frets. If you're looking at their current product line, imagine the SE245 with a 25" scale and a body that's half as thick, without the maple cap.

Couldn't tell for certain. It was sent to a shop for the pickup installation work. I didn't request anything special with the wiring so I would assume it was put in just like the old ones. After tuning pickup height the shrillness has died off and the slight quack that was there has gone away. I'm wondering if the pickups being way too low, combined with exaggerated amp settings, caused that issue.

If you can, take a few pics of the wiring. I'd be curious to see how it is wired in there.
