I think most guitar players look for a particular “feel” about the neck when trying to choose a guitar. Gibson guitar necks are generally categorized into two types. The 50’s style and the 60’s style necks. I will focus on Gibson electric guitars in this article because I have limited experience with playing Gibson acoustic guitars.
Each have a strong following and some players won’t use one or the other. I personally like both.
Another term used to describe Gibson necks is “Baseball Bat”. This term is generically thrown around to describe a very fat neck and is often associated with the 50’s style neck. As you can see from the graphic above the thickness of the neck from the fretboard to the bottom of the neck is pretty marginal. In my opinion what makes the neck “feel” thick is shoulder of the neck (the area directly below the fretboard, on the neck itself, measured from the ends of the frets). In other words the area where the greatest difference in thickness between the 50’s and 60’s neck profile.
