From the website:
"A reevaluation of string spacing, string height, fingerboard binding, and neck taper led to a new neck shape that better fits today’s traditional players. The new design offers stable grip and smooth playability over the full length of the neck."
That is interesting to me. I'd still have my LS6 if the string spacing were a little wider. Hopefully that's what they did. If so there may be another in my future.
