Yeah they are all to the meaty side. The Epi is an old school thick neck but super comfortable. The Castilla is a little later 60's style still nice and full but a bit more tapered. The Gibson is a bit more modern but still nice and full.
I can't say it's vicious but it's not wimpy, it hits the meter at 6.6k and sounds a bit Tele-ish, really can't get enough of this thing. I feel like I've wasted a lot of time with Tele's chasing something that all these guitars have in spades. The Castilla pups read low 4k area and really sound great, kind of Gretsch-y, really sounds like Malcolm cranked up. The Gibson has a Custom 5 in it and is just a pure hot rod.
