Re-stringing your Bass  
Unless you have good reason to take all your strings off at once when re-stringing - don’t. Normally strings are changed one at a time. An invaluable tool in your maintenance kit, along with allen keys, screw driver and pliers, is a string winder (make sure it fits the machine heads/tuning pegs) - a must for changing strings. After securing the string at the bridge, follow the instructions below:
1. If you need to cut off a string, make sure you use the pliers to put a right-angle bend or kink in it, to stop the string windings becoming lose or un-winding. When doing this, be careful not to put a kink in the body of the string.
2. Align the hole so that it is at a right angle (90°) to the fretboard, thread the string through (or into) the hole allowing some slack for wrapping 2 (thick) to 4 (thin) times around the post (tuning peg). Bend the string sharply at the exit of the hole (if the string has already been cut and bent - use this bend).
3. Keep the tension on the string by using the thumb and little finger as a lever as you wind it up, as shown in the diagram above.
4. Make sure the string is not wound over itself and the turns around the post (peg) look neat.
The string(s) should be repeatedly stretched and re-tuned until it doesn’t slip out of tune. After stretching and re-tuning, place your thumb on the string just past the bridge and push the string down to get rid of any slight upward curvature of the string as it goes over the bridge. The same thing should be done at the other end as the string leaves the post (tuning peg).
