You wouldn't paint a picture with dirty brushes. You wouldn't chisel a sculpture with blunted tools. So why play a banjo with worn out strings?
If you've never changed your banjo strings before, the thought of doing it yourself can be a daunting one. So much so that you may be tempted to keep putting it off. However, if you want your instrument to stay in top condition, and keep on producing a quality sound, it's important to change the strings with some regularity.
