I like all necks. I might as well be a politician with that answer!
Thing is, I find the neck drives me to a certain kind of playing. Really, the whole guitar does that too but just as far as fretting, I like most all necks because the cull out different things for me. Do I wanna rip, thinner neck. Do I want to blues it up, the bigger neck. Just a thing I noticed.
The only neck I've never liked was a Gibson Les Paul Custom. Not sure why. I can play a standard Les Paul and be happy but the bound custom neck just doesn't seem to feel right.
