Step 9. Install the Strings The ukulele has 4 strings, all with different gauge. Unlike a guitar or bass, however, these strings are not placed on the neck in order of decreasing thickness. Instead the order is as follows Topmost string second thinnest string Second string from the top thickest string Third string from the top second thickest string • Bottom-most string thinnest string Each string is installed as follows Tie a knot in the end of the string and feed the other end through the bridge slot designated for that string. Pull the string through the bridge slot until it is stopped by the knot, then bring it up over the saddle and down the neck to the nut. Pass the string through the nut slot and into the designated tuning peg as shown below. Turn the tuning peg until the string has no slack (don’t over-tighten at this stage. Leave enough initial slackness in the string to achieve 2-3 complete windings on the tuner peg when tuned.
