Kent 744 8-string electric. $600.
Made in Japan in the 1960s, the Kent 744 is an iconic and functional classic. The 16-inch scale inspires some players to set them up as mandolas, but this one currently has ultralight mandolin strings. (Any heavier and it's kind of like playing a cheese slicer.) I have a soft spot for the 744: not only does it look terrific, but a 744 was the first instrument I ever sold on 
     This is a standard sunburst model in good condition, with original pickup and screw-on tailpiece cover. Outrageous 5-ply binding all the way around. Standard gig bag included, or upgrade to custom gig bag or hardshell case. Will cheerfully set it up as a mandola if requested. See more photos, or for more information. $600.
