do you have to replace strings on a new guitar?

i'm planning to get my first guitar and i was just wondering if i have to replace the strings right when i get it because i was reading some reviews on this guitar i wanted and the people said that you needed to replace the strings or does it just depend on the brand of the guitar if the strings need to be replaced or how old the guitar is or what?

thanks
and if the strings do need to get replaced, what are some cheap but nice sounding strings?

Well, here's the deal. Guitar strings have a finite life, and you have NO idea how old the strings really are on the guitar when you buy it. Plus, if it's been hangin' around the store who knows how many people have left their finger oils on the strings. So the strings will need to be replaced with new ones, no matter what brand of guitar it is.

However, a good retailer (not some department store) would do this for you as part of your purchase. (Obviously, if you're buying it from a private party that's not gonna happen.)

If it's an electric guitar, Ernie Ball and D'Addario both make a pretty good set of strings for a reasonable price. I kinda like both D'Addario and Martin for acoustic strings. But everybody who plays will have opinions about this, and they're all probably right (for them) as long as you don't buy some off-brand or store-brand strings. All of the major string makers make pretty good ones — it's just a matter of preference.

Good luck, and welcome to the world of music making!
