How do I get to know the right time to change my guitar strings?

If your strings no longer sound full or don't hold their tuning, then it's time to change strings. If your strings look or feel dirty, but still sound good and hold their tuning, you may want to replace them, but they do not necessarily require replacement. This is a gray area where you can use your judgment

Guitar strings can wear out over time due to playing and exposure to the elements, so it's a good idea to change them every 100 hours of playing or every 3 months, whichever comes first. You can also look for these signs that it's time to change your strings:

Tone

If your chords don't chime or your harmonics don't pop, your tone might sound dull. However, if you prefer a mellower tone, worn strings might be fine.

Feel

Run your finger down an unwound string to see if it feels smooth and silky. If it feels rough or dirty, it's time to change the strings.

Flexibility

Strings should be flexible and bendable to sound their best. If they feel stiff, they're more likely to break, so it's best to replace them before they do.

Tuning

If your strings won't stay in tune, it's time to change them.

Appearance

If your strings look dirty, discolored, or blotchy, it's time to change them.
