Rodrigo the Spanish composer?
Si, unless the years have confused the brain. I DO know it was referred to by the original owner as "Bon bon" which is/was a Spanish colloquialism for "sweet" and I'm PRETTY sure it was Rodrigo's but if it wasn't it was some equally famous guitarist's guitar and definitely worth $100,000.
They also told us a story about how they went to some museum to appraise Segovia's guitar after he died. They were told NOT TO PLAY IT!! Well, they did anyways, so while the person was playing it, a string broke. They said they felt like it was Segovia's way of admonishing them from the beyond.
