To restring a nylon string guitar more easily, try tying the bass E string underneath itself in the tie block before running it through the headstock, while also running the treble strings underneath themselves on the roller post. A professional musician explains the procedure in this free video on instrument tuning and maintenance.
Hi, I'm Ryan Lynn with East Side Guitar Repair ,and in this clip I'm going to teach you how to restring a nylon string guitar. There are several methods to restringing a nylon string guitar. This is a method that I developed over the years. First, you want to bring the bass E string into the tie block like so, about three inches and tie it underneath itself so that it looks like that. Second, you want to bring the string through the roller post, take most of the slack out of the string, bring it underneath, bring the string into the headstock like this and under the string like that, grab the string on the other side of the post and loop the string underneath itself like that. Go ahead and tighten the string and what you want to do is you want to bring the slack with the rest of the string up on the outside edge of this string until you see that this string is locked in between the loop and the exiting string and then just click at about a half inch after the string. Next, for the treble strings, I like to loop the string underneath itself about three times and I tighten it up under the tie block and make sure I have good resistance. Also, for the treble strings, I like to loop it underneath itself on the roller post. I always go into the headstock, under the string, I'll grab the string there, loop it underneath itself three times. After you have the strings all strung up and tied on, clip the strings about a half inch each from your exit point and the final step is to tune the guitar. Once again, I'm Ryan Lynn, and you just learned how to restring a nylon string guitar.
