there is a magizine that is fairly popular but it is all mized up
it has a pic of a mustang and says its a duo. and then a pic of the 12 string and says its a fender mustang.
variouse stuff like that, andi see it everywhere, i thnk there is even a print up mess up that says the first jazzmaster appeared at a namm show in 1948.
cross reference everythingt you read.
