I feel like there is a difference based on my past experiences, but was looking at this diagram, and it seems the difference is a lot smaller then my perception of it - the only difference appears to be 2/32 of an inch, or 1.6mm in thickness at the nut. Seems like it should not be a major factor - it's not like, say the difference between a skinny 0.83 in Fender C and a 0.99 in nocaster, for example. Not sure how that extrapolates along the rest of then neck. I have been ruling out some options based on preference for the Pattern profile, but I wonder if that is really necessary. I do prefer guitar necks that are a bit on the thicker side, generally, and I don't like really skinny (or narrow) ones. I did play a CE24 at a store a couple of months back, and thought the neck was nice but maybe a bit too thin for my taste. I assumed it was a Pattern Thin. My new 408 has a Pattern, and I love it. I guess that translates to about 0.84 inches, which is kind of thin, actually - my sweetspot has been around .88 to .92 at the nut. But the 408 feels perfectly comfy to me. I worry that the PT, at around .78 in would feel too thin for my tastes, these days. Any thoughts?
