Guitar

The Electric Guitar is a new close-combat weapon introduced in Left 4 Dead 2.

It will make one of several strumming sounds when hitting an Infected, and, like the other close-combat weapons, will get bloodier with every kill. It appears to be a combination of a Gibson SG with a Fender Stratocaster.

The electric guitar is not really meant to be used against Special Infected, because using it on a Boomer would cover you in bile, and killing a Spitter would leave you right in the middle of the goo. It would also take time to get to a Charger, Jockey, Hunter or Smoker. Against a Tank or Witch it would do little to no damage.

Trivia

 * In the first footage, the electric guitar did not have any visible strings, but if it hits an Infected, it will make a strum sound. This has now been fixed as new videos show it to have at least three strings. It also sounds as if it were plugged-in, however it's obviously not.
 * This is one of the 4 melee weapons in the demo.
