New user here. My 14 year old son has been playing guitar for 3 years. Been getting pretty good and for the last few months has been playing his acoustic more. Then he decided he wanted a 12 string and fell in love with the Guild's at the local music store. While looking for something affordable his grandfather called out of the blue and told me a guy near him had a guitar for sell. It was a Guild f312, 1967, in pretty rough shape. But it was only $200. Has a crack in the soundboad that was poorly repaired. Varnish has been removed and new stain put on. If playable, sounds like I may have gotten a great deal. My question is this. If playable, should I be thinking about taking it to a reputable repair shop and trying to get it back to near original shape. Or, if that could destroy the sound, am I better off with a great sounding f312 that is ugly than a beautiful one that has lost its sound? Will a restoration possibly damage it?
