Hello, I`m a newby here and joined to see if I can get some idea of value and/or history behind a Guild guitar I bought online. It is a `74 D 25 C, the C designation, I assume is for color? It is cherry in color and came with a case, I`m hoping a Guild case, fits good, sounds like a Mercedes door as it closes. I`ve just gotten the strings in today (Elixir light gauge with coating) and it seems to sound pretty good. I`ve owned Martins, Gibsons, Epiphones, etc. and it sounds about the same as my old D28 Martin that was tragically lost. Did I make a good deal at $400??
