your not going to like, break your guitar by messing up the strings. the worst that could happen is to break a string, and in that case you just will need a new one.

just remember. put the string on, start to tighten, then stretch the string out all over the length of it by sort of holding it in your fingers and pulling it up while pushing down with the outside part of your palm.... sort of hard to explain. if you cant find the lesson on here, try googling it and look for a video teaching about it. its very important to stretch the strings.
