The beefy '50's neck. Made for heavier gauged strings if desiring that, and not the '60's neck that may hold heavier strings over time but then again just not as strong I know that for sure. Makes me wonder about Fenders then, and yes, I use usually a bit heavier strings but not real heavy ones because to me they stay in tune better and sound better. That is just my opinion though, but on my new guitar, the strings to me have to be changed, they just aren't cutting it from my point of view. Well, that is what I have to do -change strings.
No doubt 2014 models are coming out.

They love talking about changing pickups, changing capacitors and sometimes re-wiring the entire guitar.
I am not up to that, may never be.
