Guild? I know Fender owns them now. I'm not sure about the model number a serial number would help more. Try to find the serial number here http://www.adirondackguitar.com/Resources/Guild_dating.htm . I really hope the link helps you. Also here's a link for some prices around the year of that model http://www.gbase.com/Powered/GearList.aspx?Dealer=5bca045e-11d6-420a-9147-4d99274b7be1&GS=Y&PageIndex=1&PageSize=25&SF0=5&SD0=0&SF1=7&SD1=0&DealerId=5bca045e-11d6-420a-9147-4d99274b7be1&Grp=5&SearchBar=False
