When electric guitar strings get a bit old, do they fall out of tune easier?

since you have just replaced them make sure that you stretch them by grabbing the string with your fingers and gently pull up on it while moving up and down the length of the string several times. make sure that you have adequately kinked the strings on each side of the tuner (machine head) so that the string is not slipping. stretch all the strings several times until they no longer go flat after you stretch them. I call this the "new underwear" principal (you stretch 'em out before you put 'em on!)

old strings definitely will have problems staying in tune because as they begin to wear out they will stretch more in one spot on the string than they do in other spots. This especially true of the G string because it is the string that is bent the most. Usually when the G string starts going flat all the time it is a sign that the windings are slipping and the string is about to break.

I'm with Tony. I have used Ernie Ball strings exclusively since 1975. Never had any problems. Perhaps you are not using the correct string gauge. If you are breaking the E string a lot, then you need to muscle up and get a gauge higher. Or figure out what you are doing that breaks them. Young guitarists have a tendency to break E strings a lot. (I did LOL) With experience comes technique and you learn that you don't pick the high E string with as much force as you do the thicker ones. If you are using Extra super slinky then if you are very rough with them, you will tend to break the E string. It doesn't really matter what brand you use. If you have the wrong gauge or your technique needs fine tuning, they will break. If you are worried more about how long they last, that again is because of what you are doing to take care of them. Strings should be wiped down with a clean dry cloth after every time you play. Do that religiously and your strings can last for years. I have had the same set of Ernie Balls on my Strat and my doubleneck for a couple of years and they are just fine.

Old strings do not stay in tune and don't sound nearly as "bright". They should stay in tune better but it still could be a guitar issue. Really, six months is a long time between changing even if you don't play that much.

Strings do go 'false' with age.

It's a 'string thing'., not a guitar issue.

(Bet you 'bend' that third string a lot.)

If you have'nt changed strings in 6 months look for a real

improvement in sound with the new ones.

Not sure but you might need a new tuner head if replasing the strings dosnt work

it might, other problems might be a loose tuner, so i suggest to try and tighten all the tuners and the bridge (don't tighten the cable input, it will rip out a wire if done improperly) also your tuner itself might be bad too. its probably the strings though.
