Basic Fender Electric Guitar Setup

By Bobby Brooks

If your guitar is not playing at the correct pitch, especially while playing up the neck, you may need to set your guitar's intonation. A good guitar setup will lend to greater playing comfort if the string height is better adjusted to the fretboard and will give better intonation from the open string down the entire length of the fretboard, and in addition will help eliminate string buzz caused by the strings being too low to the fretboard; also referred to as adjusting the string's action.
The string's action is the distance between the top of the frets and the bottom of the strings. Most guitar players want their guitar's action to be as low as possible without causing the strings to "buzz" against the unfretted frets. Setting the guitar's action often depends on your playing style and your personal preferences.

Different guitars require different setups, and there are guitars that cannot be set up, their saddles and bridges are permanently fixed in one position, and therefore intonation should be checked before purchasing the instrument, and changing the guitar's strings with different gauged strings could impact intonation!
Tools you may need and want - make sure you use the correct sized tools:
Phillips screwdriver / Flathead screwdriver (for older style truss rod)
Allen wrenches or socket wrenches for truss rod and bridge
Feeler gauges
Electronic Tuner
Capo
Always re-tune after adjusting and make sure your follow up measurements are accurate.

When setting up your guitar you want to first check the height if the nut. I spent countless hours trying to setup proper intonation; I set the saddles as far back as possible and I still was not getting proper intonation at the 12th fret, only to realize after much investigation that the nut had not been and often are not properly cut from the factory. If you are not sure what the guitar nut is check out basic guitar anatomy.
To check the height of the nut first press down on the strings at the third fret, using a capo at the third fret will make the task easier. A feeler gauge between 0.15 and 0.20mm should pass through at the first fret on an electric guitar without touching either the string or the fret. If the string touches or if the gap is too great, then the nut setup is incorrect.

The next step is checking the neck curvature against a string gauge and making sure the neck bow is sufficient and not too flat or too bowed; and adjusting the truss rode if needed - a neck should never be completely flat. On an electric guitar press down on the strings at the first fret and at the fifteenth fret at the same time using a capo or capos, if possible, and check the height of the strings at the seventh fret. The height at the seventh fret should be between 0.10 to 0.25mm.
The truss rod is typically a single action or dual-action metal bar or graphite bar which runs the length of the neck giving the neck resistance against hundreds of pounds of pressure inserted by the guitar's strings. Single action truss rods are threaded on one end which allows you to turn the bar to increase or decrease the pressure against the pressure of the strings. A double-sided threaded bar allows you to increase or decrease the tension of the strings before running out of adjustment. If the guitar is bowed backwards the strings will be too close to the fretboard and buzz in the middle of the fretboard.

If the gap is too large you will need to tighten the truss rod to increase the bow in the middle which will bring the strings closer together; and if the gap isn't great enough for the feeler gauge to pass through freely you will need to loosen the neck curvature by loosening the truss rod. If needed, check the guitar anatomy to locate the truss rod.
To increase relief, you will want to loosen the truss rod by turning it counterclockwise, and by turning the truss rod clockwise you will decrease the relief and tighten the truss rod. An adjustment should be done turning the truss rod only about a quarter of a turn at a time and always tune the guitar after each adjustment to insure proper tension to correctly check the adjustment.

Do not force the truss rod! If you are having trouble moving the truss rod the rod could be turned as far as it can be adjusted. If this is the case, you will want to take the instrument to a qualified luthier. In some cases, the guitar may need to settle overnight after an adjustment to insure you are not over-tightening the truss rod.
The third step is adjusting the bridge height. On an electric guitar the gap at the twelfth fret between the string and the fret should be about 1.8mm on the low E-string and 1.4mm on the high E side. You can adjust the saddle height for each string by adjusting the two setscrews on each side of the strings: thus, lowering or raising the guitar's action.
x
Adjusting the saddle height higher will increase the string tension thus making it more difficult to bend the strings while playing; therefore, it is advisable to adjust the height according to your playing style as well as for comfort and intonation.
The fourth step is adjusting the saddle depth, which is either moving the saddles away from the back of the guitar or towards the back of the guitar. If the fretted note is flat, adjust the saddle towards the neck. If the fretted note is sharp, adjust the saddle back towards the bridge. Remember - flat forward, sharp back!
x
Start by tuning the six strings on your guitar to their proper tune using an electronic guitar tuner. Once in tune starting at the twelfth fret low E-string check and make sure the string is still in tune. If the note on the twelfth fret against the same string in open position is too high, it means the saddle needs moved back towards the back of the guitar and if it is too low it will need to be moved forward away from the back of the guitar.
Do not strip the screw heads when adjusting intonation; you may need to loosen the string tension when moving the saddles forward. Turn the screws incrementally until you determine the required pitch adjustment. A proper guitar setup is not an easy task, and if often better left up to a trained guitar luthier, who can often be found at your local instrument dealer's shop.

Additional Tip: You may want to adjust the height of the pickups - the distance from the strings.
Bridge pickup = Low-E string: 2.5 mm / High-E string: 2.0 mm
Middle pickup = Low-E string: 3.0 mm / High-E string: 2.5 mm
Neck pickup = Low-E string: 3.5 mm / High-E string: 3.0 mm
