The Bluesbox Collection This close up of the face shows the sunburst solid spruce top with six-ply binding and inlaid rosette. The back and sides are laminated mahogany, which means that this guitar more closely resembles the Gibson J-45 then the Advanced Jumbo model that it is supposedly based on. The fingerboard has snowflake inlays with a block inlay at the twelth fret. The headstock is faced with rosewood and sports mother-of-pearl inlays. The tortoise shell overlay seen here was installed by me to mask the repair work. The back of the head shows the gold Schaller tuners I installed (Epiphone removed the original tuners before they sold the guitar - I also had to install the nut, saddle and bridge pins). I repaired the break and inlaid a "volute" - which is an exterior brace - to stiffen the join, then I repainted the back of the head black, rather than try and duplicate the original sunburst.
