Although Holdsworth is pictured in All Night Wrong with his custom headless guitar built by luthier Bill DeLap, he still relies on his signature model Carvin Fatboy. "When we travel to Japan, I often take the headless guitar because of size limitations. Now, Carvin and I are in the process of making a headless version of my signature model, because I really like the way the headless guitar hangs on me. It's so balanced." Holdsworth strings the DeLap with a LaBella .008 set, and his Carvin with a .009 set. His pick is a 1mm Dunlop.
