I remember reading a story about a guy who had recently gotten hired as a guitar tech for the Ramones. Wanting to make a good impression on Johnny Ramone he decided to restring his guitar for him right before the show. He removed all six strings and Johnny's Mosrite guitar literally fell apart in his hands http://www.bonairmax.com . The string tension held the whole guitar together! What's worse, Push/pull the string back through the bridge slowly making sure it does not drag across the body. You don't want restringing your guitar to result in refinishing your guitar! Next, unwrap the appropriate new string. Insert it through the bridge of the guitar, over the saddle, up the neck, over the nut and into the hole in the tuning post. Again make sure the trailing end of the string doesn't drag across the guitar body.· Start turning the tuner by hand making sure the string wraps over the top of the tuning post. Ideally you want to have 3-4 wraps of the string around the tuner, but this in nothing to stress over. · Turn the tuner until the slack is out and the string is properly seated in the nut and over the bridge saddle. · Next clip the excess string off close to the tuner and use your string winder to bring the string up to pitch.Use your digital tuner and tune to pitch.
