Special note on strings
There is no warranty on strings. Manufacturers recommend that you change the strings every 3-4 months. It is always a good idea to keep an extra set of stings to replace any that may break. You should always wipe down your strings with a clean dry cloth after use. If you store your instrument, you should consider changing the strings when you pick it up again.
