This Martin D-28 had it's Headstock broken on two different occasions thus, drastic measures were needed to make it hold together. I inserted 3 carbon fiber rods to span the break. It got put back together with just a bit of finish touch up at the end.
I am currently prepping two guitars to take out to both the Boston Guitarfest starting June 15th and then to the Guitar Foundation of America Convention the following week. Should be fun.
