My friend needs money and has offered me his 12 string that William Cumpiano built in 1982 as Stringfellow guitar. He is too far away for me to play the guitar. He is in a bit of a hurry and never wanted to sell any of his personal guitars and is even having trouble getting me a pic in time. He says it is amazing but I can find no references to any of Cumpianos guitars by anyone on the web just many re: his book on lutherie. I would like to help my friend out but I would also like a few more opinions about the guitar from unbiased sources before I buy it. Have any of you had any experience with guitars built by William Cumpiano? What do you think such a guitar would be worth? Cumpianos website indicates that he charges about 3500 for a new guitar although there is a wait to get one made.. This one has mahogany back and sides and bearclaw spruce top.
