When to change guitar strings on your guitar or bass
The short answer to this question is between 15 to 30 hours of play! and here’s why:
As you play, the strings will collect dirt and oils from your hands (You should always try to remember to wash your hands thoroughly and dry them well also before playing your guitar as the oils and dirt on your hands can have a bad effect on your strings and over time the fret board itself). This causes the strings to become dead sounding and to vibrate unevenly along their length (also causing tuning problems). Dirt and oils get into the winding of the strings and down inside to the core of the strings where it can cause corrosion of the core. If your hands are dirty or if your hands perspire when you play, this will shorten the string life also.
Wiping the strings off each time you are finished playing will help prolong their life (a clean cotton cloth works well for this). Also, if you bend strings or play hard this will cause flat spots on the strings especially at the fret locations, shortening their life. You will start to notice small ridges or crests forming in the strings by the areas you hit the hardest. When you start to notice this or you start to get a dead droney sound then it is time to change the strings.
Also for you squealers out there you will notice that you will have to give just a bit more effort to get your harmonic as the strings get worn from the repeated pounding of the squeal.
When you change strings is dependent upon how often you play, the way you play, your playing style, your care of the strings, and the effect your hands have on the strings (the cleaner you keep your hands the better it is for the strings and the fret board).
