Instructions: To tune your guitar, first you need to know what tuning you want the guitar to be in. The standard tuning for a 4-string Bass Guitar is EADG (from low to high). If you want to tune it in standard form then you don't have to change any of the notes above, because it is initially set to EADG. If you want a different tuning then try some of the presets on the right side of the tuner. If you don't find the tuning your looking for then you have to adjust the notes manually. Once you have set up the notes and have the correct tuning. Then click on the buttons one at a time and then tune your corresponding guitar string to the note. The thickest string on the guitar is the 4th string, and the thinnest is the 1st string. It tells you what string it is on each button. Also, be careful on how high you set the notes, because i have included notes on the tuner that would probably snap average guitar strings or might damage your guitar if kept at a very high tuning for a long period of time. Good luck.

Tip: Make several passes tuning each of the strings. For example you might have noticed that if you have tuned all the strings once, and then back to the first one you tuned, it might be off a little bit. This is because you are increasing or decreasing the tension on each of the strings as you tune it and the instrument's body might bend ever so slightly due to this difference in tension. This causes the other strings to slightly change in pitch. So make sure you keep on checking and tuning the strings until all are in tune, so make several passes.
