John S. Konesky (born November 19, 1980) is a Grammy Award winning American guitarist, record producer and occasional actor. Konesky was born and raised in Columbus, Ohio, where he performed in a band with friend John Spiker. Through a mutual friend, he and Spiker met Tenacious D guitarist Kyle Gass, who was recruiting musicians for his Trainwreck side-project. In 2003, Konesky and Spiker would both re-locate to Los Angeles and become the electric guitarist and bassist for Trainwreck. In 2005, Konesky and Spiker performed on the second Tenacious D album, The Pick of Destiny and would then perform live on The Pick of Destiny Tour, making them (alongside drummer Brooks Wackerman) additional live members of Tenacious D. In 2010, Trainwreck split up, which lead him and Gass to form Kyle Gass Band. In 2009, Konesky and Gass also worked on Guitarings, their own YouTube channel. In 2012, Konesky formed Wynchester alongside Kyle Gass Band frontman Mike Bray. Konesky would also continue to record on the third and fourth Tenacious D records - Rize of the Fenix (2012) and Post-Apocalypto (2018). In 2015, Konesky won a Grammy for his recording of Tenacious D's recording of "The Last in Line" for a Ronnie James Dio tribute album. Konesky would also reprise his role in Trainwreck when they re-assembled in 2018. Outside of projects with Gass, Konesky and Spiker have both recorded and performed live with John Carpenter and Ronnie Vannucci Jr.'s Big Talk. Konesky has also provided guitar on many soundtracks and scores such as Documentary Now!, The Hangover Part II and The Runaways, as well as artists such as Sea of Air, Céleigh Chapman, Molly Bryant and Eat the Gun.
