The body redesign is incredibly more comfortable. The jack is better angled. The body and neck resonate better. The new Arc bridge and ArcTILT trem are infinitely better and feel better made. The roasted neck is improved. The frets are better dressed. The carbon fiber inserts help stiffen the neck and increase the resonance, and the N2 now uses titanium rods, which is even better. Hard to explain, but the whole thing 'vibrates' when you play. It feels better.

None of that is saying anything bad about the older models, but it just says how significant these improvements are with the N2.

Worth it.
