That guitar is an x-ray of a 64 Tele reissue, part of Project X-Ray, getting a deeper picture into classic guitars. It really shows how bear-bones the thing is. There's also shots of some harp guitars, guitars made by C.F. Martin and Orville Gibson, and some golden-era Gibson's and Martins. The project started to see if there's a difference between the Gibson instruments built pre-WWII and those built by the "Kalamazoo Gals" during the war. Check it out!
