Hamilton endorsed ESP Guitars in the 1990s, and is best known for playing ESP Horizon guitars with either a Floyd Rose or Wilkinson tremolo, and DiMarzio Airzone pickups. In 2006 ESP announced a Page Hamilton signature model, featuring a single DiMarzio Airzone pickup and Wilkinson tremolo. In 2009, ESP announced a further signature model guitar, this time modeled after Page's own ESP Horizon Custom, featuring a distressed magenta finish emulating the original guitar's road wear and character and, again, a single DiMarzio Air Zone pickup. He has also used guitars by PRS and G&L.
