After a couple of listens, those clips are very similar, perhaps a hint more brightness from the Evo, but I could well be imagining it.
As for pickups making a difference, I have changed a few because I was not happy with the tone from certain guitars I own, and I can say without a shadow of a doubt that pickup changes can have a big effect.
I changed the stock V8 in a 1570 to a SD Invader, and the difference is night and day.
I also changed the stock SD Jb in a LTD MH-1000 to a Dimarzio D-Sonic, and again, it completely changed the tone(for the better).
I'm currently in the process of swapping out an EMG set in a Ltd Mh-400 for something a bit more organic, and I'm also putting an Evo in a short scale (24.75) Charvel Fusion Custom to tighten it up a bit.
Back to the op, i'm eagerly awaiting the SS clip, and I hope you can get a tone you are happy with.
Rock on!
