I need new strings for my guitar and this is basically the first time I've needed them so i was wondering ..

How often do you need to change your strings ?

and

What sort of impact do strings make on the overall sound of a guitar, I'd imagine some are more suited to some styles, but in general, does it make a difference ?
Fuck it.

i change them at least once a month, more when i was gigging and its more about what you like than anything they dont make strings for rock or country but you wont use extra light strings for really drop tuned metal

you will notice that new strings sound alot brighter though and may need to be broken in
