Exactly how long your guitar strings will last depends on a number of factors, including the type of strings you have, how much you play, the humidity of your climate, and even the acidity of your sweat. Eventually, you will notice that your strings no longer sound as "lively" as they used to. They will sound dead. Generally, every 2 months is a good rule of thumb - but go by the way the strings sound. You will eventually be able to tell exactly when they need changing.

Here are some tips for prolonging the life of your strings:

• Wash your hands before playing your guitar
• Wipe off your strings with a soft cloth when you are done playing
• Use coated strings. The coating protects your strings and makes them last longer
