Have been thinking of buying a Ric now for a week or so, but I am wondering if I need to be looking at certain years or are they all (4001/4003 models) going to sound essentially the same and have the same quality? I think I can get a 2012 4003 Maple Glow traded to me, but dont know if I should look for an older one (70's or around then)? Any advice would be great!
