Setting Up Your Bass Guitar: Nut Action Height Adjustment
(Step 3 of 4): by John Caruuthers
saddles. This adjustment is a matter of personal preference. There should be a gradual decrease in
height from the E string to the G string. Table 5.2 should be used as a reference for adjusting the Bridge
saddles.
5.2.1
Checking String Height
Using a calibrated metal ruler, measure the height of the string above the 12
th
Fret as shown in Figure
5.2.1. Check the measured height against the desired height in Table 5.2.
5.2.2
Bridge Saddle Adjustment
1.
If incorrect, adjust the string saddle height clock wise to increase the measured distance or
counterclockwise to decrease the measured distance. There are 2 adjustments on each saddle
that should be adjusted simultaneously so that the saddle remains level.
2.
Repeat on the next string until all strings have been adjusted.
5.3
Nut Action
Setting the string action that is right for you starts at the nut. The slots
should already be close, but you might want to make some adjustments.
The adjustment of the nut height requires special files and can be
performed at a future date. If you are unsure how this action will impact
your specific playing style, we suggest that you measure and record the
height for all strings in Table 5.3. Should you decide to make this
adjustment in the future, you will know which strings need to be
adjusted and by how much.
5.3.1
Measurement
1.
Using a .022 feeler gauge, measure
& record the space between the
first fret and the bottom E string –
the gauge should be a snug fit if
spacing is correct.
2.
Repeat on A, D & G strings.
5.3.2
Nut Adjustment
If the gap is wider than .022”, the slot needs to be deepened.
1.
Detune the tuner for the string you are working on so that it
can be removed from the nut.
2.
Using a small file or round needle file, carefully deepen the nut slot. Make sure when you
deepen the nut slot, the file is angled down toward the headstock. This will ensure the string
sits on the edge of the nut closest to the fretboard.
