I wa a vintage guitar dealer for eight or nine years. It was a hobby, mainly, but I sold nationally through display ads in Vintage Guitar magazine and did three or four shows a year. Bought and sold a couple hundred guitars, probably. Moved to Boston area in 1997 and quit the business, keeping a dozen or so great guitars and 10 or so great amps.
Happy to help you any way I can. Tell me what you have, including conditions, originality, dates, etc., and I'll try to give you some idea of value. Can make suggestions about how to sell 'em, too, if you want.
