You're moving to a great town for music and gear ... I've lived in better towns for live music ... I guess the biggest downside is live music is not centralized, it's scattered across many neighborhood bars in a 30 mile radius.
As Bill (RedRider) mentioned, it's probably the biggest gear mecca outside the LA area. DestroyAllGuitars, Fatsound, Indoor Storm and Soundpure have amazing gear ... then there's all the local builders.
I'm from the Northeast, and Raleigh feels like 'home' now.... great place to live.
