Jack White - Very rare 1957 Gretsch White Penguin. One of the rarest guitars in the world, it can be seen in the video for the song “Icky Thump.” For the Raconteurs, he designed a Gretsch clone, which he has dubbed the “Triple Jet”. It is a double-cutaway Duo Jet with a pickup booster, and features a solid copper top. It also has a Gretsch logo that was only used on a few guitars in 1912. It is not a factory Grestch, as it was built by luthier Randy Parsons of Seattle.
