3 string acoustic, 23" scale, built for a friend who collects M&M stuff. I am betting he does not have one of these. Used M&M colors and for you trivia folks, violet was an original color and was replaced in 1949, so I thought it was fitting to use violet in his initials on the peghead and at the 12th fret. No springs, I put soundholes on the left and right sides. sounds pretty good.
