I had em in a LP type (ESP ish) for a while. First of, that is not the best placement for them. The short scale and load of thick mids, as a LP does and this one was an especially heavy beast, did not make a good pairing. For the bridge that is, the neck was ok. I took em out and replaced them with a Stockholm and a Supermassive, which work much better in that axe for the drop Bb In Flames-ish I was using it for. Now those are also going out since I want to tune it up, so RYs are going in there.
My Aftermath is now sitting on the side till I get a fitting axe, which would be superstrat style. Perhaps even a baritone.
Now for the reasons I shall finally describe the tone. The bridge is a machine. Seriously. Dry as the desert, center mid focused voicing (thus the baritone idea and why it did not fully work in the original axe), super punchy tight as freaking heck bottom end, agressive high end. It is so surgical that it does feel like machine. Stop start riffing is so easy here. The guitar needs to have a proper amount of bottom end though and probably not be center mid heavy (low mids prefered, high mids ok), and not be extremely bright. I imagine a lightly scooped and bit mellow axe would be perfect.
Style wise this can crush all extreme metal sounds easily imho. The amp really dictates here. It´s not the most versatile pickup, but I believe it can go from big death metal, to djent, down to hardcore punk stuff, etc. I even got it to deliver what was not a bad pop punk sound, as it´s agression paired with my Tiny Terror in a way that made it sound more American.
It´s definetly different from what you already have.
The neck was a real joy to me. I think it nailed the early John Petrucci sound (Awake era). One day I´d like an axe with this and a holydiver in the bridge as I think that could nail that early sound. Anyhow, it is very full, fluid as heck, smooth, yet does not loose its bite. Really just listen to an Awake solo or so. Sides that it can of course do modern shred and ambient sounds.
Ok, so that is my stream of conciousnes rant on the Aftermath. Hope it helps a bit.
