I noticed that guitar last night at the Phoenix show. It looks like a Gibson Melody Maker in Sunburst, with a little bit of custom pinstriping ala BFG of course. I believe that Billy's first guitar as a child was a Melody Maker, if I remember the interview correctly. Recreating his original Melody Maker, or a custom painted reissue model could be a cool Gibson Custom Shop idea.....haven't heard of anything in the works though.
