just changed my own strings for the first time. It's not too hard. bought a winder tool that came in handy for pulling pegs, and tuned the strings before I started and as I progressed, string by string. didn't know I needed to change them until a good friend, and guitar virtuoso informed me that my strings were "dead". When I played the new strings, side by side with the old strings, I could tell the difference immediately. definitely get the winder tool. it's worth the $$. About $15 or so.
