oh ok, as long as you're sure it's a direct swap, go for it (as long as you like the guitar enough and are willing to sink that much money into it).
The edge isn't low profile, the edge pro (and lo-pro edge) is. That's the big difference. There are a couple of other smaller ones, too, but that's the main difference.
would be worth swapping the electronics, yeah. I'm not too well up on it as i've never actually done a swap, but i know that my guitars with quality electronics sound noticeably better- they make the tone and volume knobs usable.
