CHANGING GUITAR STRINGS AND INTONATION:


CHANGING STRINGS

            Get a string winder. Pluck the low E with your right hand and unwind with your left and hear the tuning flatten to a metal rattle. At this point there should be enough unravelled string to pull it up and off the tunning nut, where you can unwind and pull the string out. Then pull the bottom end of the string by the eye out of the body. Repeat five times.
            Once the old strings are off, clean and polish the neck and body and everything with lemon oil. Inspect the nut bridge, frets and saddle bridge for wear. Tighten any loose screws.
            Start restringing with the low E: Send the bare end of the string through the back of the saddle bridge and then through the eye of the nut. Pinch the string with the left hand after placing the string in the nut bridge and pull the string with the right index finger about three inches from the body. Then grab the string at the nut bridge with the right hand and bend the string 90° around the tuning nut with the left hand. Start cranking the tuning nut while keeping tension on the string with the right hand at the nut bridge. Turn it all the way up to a low E, pass it sharp and back, exercising the string. Repeat five times.
            Tune the guitar, push and pull the strings on the fret board as you would play them, and tune again—exercising the strings now lessens tuning during play.

INTONATION

            There should be a slight concave curve in the neck. Look down the top of the neck from the bridge like a sighting a rifle to see if it curves. If you have a feeler calipers handy, 4/64” (1.6mm) is the standard distance between the 12th fret and the strings. Adjust to your playing style if need be.
            The 12th fret is one octave higher than open tuning. Intonation is the open note in tune with the 12th fret octave note. If sharp, turn the saddle screw counterclockwise, moving the saddle toward the neck. If flat, turn it clockwise. Repeat for all six then strum a chord high up on the neck. It shouldn’t wobble.
