Just an FYI .........
Having built 20+ electric guitars (mostly Tele shaped but strats also), I've come to really like the
Alnico 2 pickups both in humbuckers and in single coils. (and in humbuckers, Alnico 3 in the bridge) Alnico 2 strat pickups are not nearly as common as the Alnico 5 pickups & I prefer the Alnico 2 more.
Both of my Tele's with H-S-H pickups started out with DiMarzio Fast Track 1 or Cruisers as the "S" middle pickup. I ended up replacing both of those middle pickups with the Calig alnico 2 strat pickup for around
$20.
It's a super nice pickup! I love the tone of it. Very warm sound to it and a true strat sound to my ears. I have NO idea if any of their other pickups are any good or not?
I just built another Tele using a set of Alnico 2 strat pickups where the middle one is reversed wound for a hum cancelling feature in 2 & 4 on a 5 way switch. I also added a mini-toggle to the guitar to combine the neck with bridge pickup when I want.
I'm VERY happy with these pickups! I've mostly used DiMarzio's over the years but also StewMac's "Golden Age" single coils and humbuckers and some Seymour Duncan pickups.
As far as warm strat tones and reasonably nice "quack/percussive tone" in 2 & 4 position, these are a winner for me! And for a single coil, I think they are relatively quiet (I use copper foil inside the control cavity) and in the 2 & 4 position - they are certainly as quiet as any humbuckers I've used.
Tone wise, I'd describe them as a very
clear tone with warmth. They are somewhat percussive, but that could be connected to body and neck woods on the guitar? Since my amps tend to have reasonably high gain, I strongly prefer lower gain pickups. Chording and rhythm with these are great, you can easily hear each note. Zero mud. I think one would probably want the overdrive on or a Timmy or Zendrive or something to boost for good lead solo's.
The set I got has good definition between the neck, middle and bridge & the middle pickup actually has a good tone to it which I will use.

* This guitar is actually solid instead of semi-hollow like I typically do. It's basswood capped by a 3/16" maple slightly figured top.
