Hi, Cara,

I'm Chris and I'm always on electric. Guitarists who play on stage or in bands sometimes have to change them on a weekly basis, as strings wear down quickly. Practice, however, every 1-6 months is just fine.

It all really depends on the quality of the strings you buy. Strings will tell you anyway, by the tone (they become flat and dull) and by the darkened lustre that fades from shiny silver.

Regards, Chris.
