Can an electric guitar kill someone?

Answer 1

If you hit them hard enough with it, or if you play it in wet conditions, and the polarity is such that the guitar is grounded hot... check out this link... http://www.guitarnuts.com/technical/electrical/safety/index.php

also check this info on guitarist kieth relf of the yardbirds, i got it from wikipedia.:

Keith William Relf (22 March 1943 - 14 May 1976), was best known as the lead singer and harmonica player of The Yardbirds. After the Yardbirds broke up Relf formed the acoustic duo, Together, with fellow Yardbird Jim McCarty, followed by Renaissance which also featured his sister, singer Jane Relf, then hard rock group Armageddon. Relf also produced tracks for artists such as folk-rock band Hunter Muskett, the acoustic, world music, group Amber, Saturnalia and Medicine Head, with whom he played Bass Guitar.

Relf was 33 when he died from electrocution, at his home, while playing his improperly grounded Electric Guitar.[1] At the time, Relf was rehearsing new material for the regrouping of the original Renaissance line-up, called Illusion.

Relf's posthumous 1992 Rock and Roll Hall of Fame induction with the Yardbirds was represented by his wife April, and son Danny.
