I just purchased a new Core model custom 24 from GC. It looks great, plays great, not a flaw anywhere. When I checked the SN I found it a 09 model. How they had a guitar that long without selling it seems funny to me. It has a letter from Paul Reed Smith identifying it as a July300 series that was hand picked etc. It's also a 10 top. Should I be concerned about buying a "New" 5 year old guitar?
