The Epi Ultra's, PRO's and a few signature models like the Joe Bonamassa tend to be a higher quality build and pickups than the rest. The lower and middle Epi's are a case by case basis in my experience. Some of the Custom's are OK, and some have their cheap pickups. The necks are usually their slim-taper shape and thickness, which feels pretty good to me. The occasional '59 rounded D is a bit thick for my preference.

YMMV
