Moderators, if this is in the wrong forum, please accept my apologies (and move it accordingly): A co-worker says he has a Peavey Foundation, three tone sunburst, made in the 70's and never played. He wants to get some idea of its worth. Where can he (or I guess me, since I am on here asking) get that kind of information. I've skimmed eBay and saw other Peavey Foundations, different model years, ranging from $200 to $500. Thanks in advance.
