This was my first guitar cake. I had my husband measure everything on his guitar to try to get as much as possible to scale. The neck was all gumpaste, and because I had black, I want ahead and made all of the accents on the actual body gumpaste. Sour cream pound cake with butter cream icing, and painted mmf. Without a pic of the groom's guitar I was pleased with the reaction and found that it looked just like his. TFL
