Guitar

"Grabbing an axe."

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

Like all melee weapons, the Guitar takes place of the pistols slot which means players will have a tactical choice on whether to pick whether they want ranged weapons with reloading and lack a punch or a weapon that must be used in close quarters but is an instant kill. Also, each time it is used to kill an infected, it gets blood spatter on it. It appears to be a Gibson Les Paul Doublecut. Whenever this weapon makes contact with a physical object, it makes a random strum noise.

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.
 * The Electric Guitar could be a tip of the hat to Electric Guitars used in the video game Dead Rising, as if either guitar makes contact with a zombie, it sounds as if it as been hit while it was plugged into an amp. A few of the slammed chords sound identical.
 * Occasionally Ellis will refer to this weapon as an axe, referencing how many rock artists refer to their guitars as "axes".
