Ah yes, the old pickup dilemma. It's really hard to say what pickups one should get. It's so individual and depends fully on what type of sound you're going for. However, there are a few differences in quality. I.e just because it's a humbucker doesn't mean it's a good pickup. Gibson, Seymour Duncan, Dimarzio etc all make great pickups. And it's def worth spending a couple extra dollars for something like that rather than an Epiphone humbucker.
I suppose as long as the pickup you want to coil tap is humbucker it should be possible. It doesn't work if it's a single coil pickup.

Hope this helps!
