Guitar

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

Like all melee weapons, the Guitar takes the place of the pistol slot. It has a slightly slower attack rate than most melee weapons, but appears to have slightly longer range than others and can decapitate Common Infected. Each time it kills a Common Infected, it also gets blood splattered all over it. The Guitar appears to be based on an Ibanez GAX70, and when it makes contact with a physical object, it makes a random strum noise.

The Guitar does friendly fire damage to other Survivors, and can also instantly kill or severely injure Special Infected. However, most Special Infected either have destructive effects when hit or aren't worth the trouble of getting so close, so you're usually better off shooting them.

Trivia

 * In the first footage, the electric guitar did not have any visible strings, but if it hits an Infected, it would make a strum sound. This has now been fixed as new videos and the demo show it to have three remaining 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".
 * The finale of Dark Carnival has a lot of Electric Guitars for the Survivors to use since they're on a stage.
 * Like the Katana, the Guitar has been viewed as a somewhat unorthodox weapon for a zombie outbreak. However, it was probably added to set a mood that Louisiana was abandoned during the events of Mardi Gras or one of the many festivals that take place in Louisiana.
