I have never changed strings on my Fender Standard Jazz, and I've had the guitar for over a year. The strings are the factory roundwounds, and so far I'm extremely pleased with them. They haven't showed any signs of dying (knock on wood) but I know they will have to be replaced before too long. The only cleaning I have done on them is wipe them down with vinegar twice. So, what do you all think of Fender Strings? For those of you who like them, what do you use (i.e. Nickel, roundwound). I like the sound of the roundwounds I have now, as you can do just about anything with them. Just curious about what you all think, and if you don't like Fenders, what do you use?
