The Ultimate Guide to The Perfect Bass Setup
version 1.0
Introduction
In my honest opinion, every bass player should know how to set up his or her own
instrument. Even though some bass players know how to do it, most turn to a professional
to do it for them.
So, you might ask, "Why should I learn how to set up my bass if a professional guitar
maker (or luthier) can do it for me?"
In time, you will probably discover more reasons, but for now, I will give you two:
First: because if you learn to do it yourself, you will save a lot of money, time and
travel.
Second: the setup will be much more customized according to your personal
playing style.
The process itself is relatively simple, but it requires a lot of experience before you will be
able to do it optimally. I'm not going to lie to you: you won't learn how to do it overnight,
but each time you make adjustments to your bass, you will do it better than the time before
and one day, you will reach a point where you can set up your own instrument in terms of
your personal criteria and needs better than any professional ever could.
As far as I know, there is no other definitive, simple and precise guide available on the
market about how to set up an electric bass.
This Guide was written especially for you and for those bass players who would like to
learn this process, but don't know where to begin.
Even though it has been written with the electric bass in mind, it can also
be used for setting up electric guitars or other similar instruments
because the procedures are exactly the same.
Read it, then read it again and make it an indispensable part of
your instrument maintenance toolkit.
This is why I have written this book, as my gift to you.

Before You Begin
Tip #1
Keep in mind that manipulating the truss-rod or
other elements of your bass is prohibited while
your instrument is still under warranty. If this is
the case, I recommend that you take your
instrument to a professional luthier. If you are
a complete novice, I also recommend that you
practice first on an inexpensive instrument
before trying these procedures on your own
instrument.
If something goes wrong with an instrument
you aren't using anyway, your mistake won't
cause any problems and you will learn from it.
Remember that trial and error is the best way
to learn, as long as you learn from your
mistakes so that you won't repeat them.
Choosing a Place to Work
During the winter, abrupt
temperature changes, both
outdoors and indoors, may
cause the neck of some
instruments to move more than
it normally would.
This is why you should allow
the instrument time to adjust to
room temperature before
making adjustments to it
during this time of the year.
This may take a couple of
hours. Remove the instrument
from its case and place it in a
location away from any direct
heat sources.
You should choose a place that has enough
room to give you unobstructed access to your
instrument. The best option would be a table
that is large enough to fit the whole instrument.
Place a blanket or towel underneath your instrument to avoid scratching it

Tools
Before you begin, you should have all of the
necessary tools
ready:
1. Standard or
Phillips
screwdrivers,
depending on the make of your
instrument, in order to remove the truss-rod
plate if your bass has one or to unscrew the
battery plate if your bass has active pickups
2. A battery or batteries, if your
bass has active pickups;
you will normally need a 9v
battery or two of them in the
case of an 18v bass
3. A set of gauges to adjust the height of the
strings; if you don't have one, you can
improvise with a credit card
4. A new set of strings
5. Allen wrenches, if you
need to adjust the
bridge
tester
6. OPTIONAL: A battery
7. A brush and cloth or better yet, a chamois
the
8. Spirit of turpentine for cleaning
fingerboard
9. Templates for
determining the
curvature of the
fingerboard; if they aren't
available, you will find
some cut-out templates at
the end of this book here
along with specific instructions
on how to use them correctly
10. Small wire cutters to cut the strings
Tip #2
If your instrument needs
a thorough cleaning, it
will be necessary to
remove all of the strings in
order to access every part of
it.
Remember that routine
adjustments that don't
involve
a thorough cleaning
won't require removing
the strings and in fact,
it is highly
recommended not to
remove them. This
could cause the neck to
become dislocated, due to the
tension of the strings not
compensating for the tension
of the truss-rod, and as a
result, it will take even longer
to return the instrument
to its correct
alignment.
Remember:
During routine maintenance,
you should change the strings
one by one.

Getting the Instrument Ready
If a lot of time has passed since the instrument
has been adjusted, it would be a good idea to
give your bass a good cleaning.
For this, you will need a brush, a piece of
flannel or a chamois, a cleaning product for
finished surfaces or one that is made especially
for guitars and, last of all, walnut or teak oil and
spirit of turpentine.
1. Remove the strings
2. If you are going to make adjustments after
cleaning, it won't be necessary to loosen
the truss-rod.
3. If you are planning on leaving the
instrument without strings for more than 7-8
days after cleaning it, it will be helpful to
loosen the truss-rod so that the neck won't
warp, which can be very difficult to correct
later on.
Tip #3
If you are going to make
adjustments after cleaning, it
won't be necessary to loosen
the truss-rod in the neck.
If you are planning on leaving
the instrument without strings
for more than 7-8 days after
cleaning it, it will be helpful to
loosen the truss-rod so that the
neck won't warp, which can be
very difficult to correct.
Remember:
Loosen the truss-rod if you are
planning on leaving the
instrument without strings for
more than 7-8 days.
Cleaning the Fingerboard
If you haven't cleaned the fingerboard up until now or if a lot of time has passed since you
last cleaned it, you should take advantage of this opportunity to clean and polish the wood.

Maple Fingerboards:
If the fingerboard is made from maple and is varnished like the rest of the instrument, you
should use the same cleaning product as you use on the whole instrument. In this case, it
should be a product for finished wood surfaces. You should gently rub the surface of the
fingerboard between the frets with a cloth and a small amount of cleaning solution. This
should only take a few minutes.
Rosewood, Ebony or Brazilian Ironwood
Fingerboards
As a rule, these woods are treated with an oilbased finish to prevent them from drying out.
In this case, to clean the accumulated grime,
we will use spirit of turpentine.
Spirit of turpentine is a suitable product for
cleaning wood and, unlike mineral solvents,
will not cause it to dry out.
You should moisten a clean, dry cloth with a
little bit of solvent and then gently rub the
surface of the fingerboard until it is completely
clean.
Let the fingerboard dry for about 10 minutes
and then apply walnut or teak oil to the
surface, rubbing lightly. Let the oil soak in for
about 5 minutes and then remove any excess
with a clean, dry cloth or paper towel. The
wood will usually expel any excess oil, so you
should clean it several times at 5-minute
intervals.
Cleaning the Bridge
Basically, we will want to rid the bridge of any
small particles and debris that have
Tip #4
Spirit of turpentine is the
essential oil of turpentine.
Turpentine is the resinous sap
from certain types of pine
trees (originally from the
terebinth tree). When
turpentine is distilled, two
products are obtained: the
volatile, liquid essence, which
is spirit of turpentine, and a
solid resin, called rosin.
You can use spirit of turpentine
to clean ALL parts of the
instrument that are made from
untreated wood or wood with
an oil-based finish.
Remember:
Never use other solvents, such
as nitro solvent, alcohol or
acetone in place of spirit of
turpentine.

accumulated between the moving parts. A brush is very good for this purpose.
Afterwards, we will want to lubricate all of the moving pieces, such as the pins and the
saddles that make direct contact with them. In general, bridges are made up of a number
of metal pieces, which usually have a chrome finish. This finish doesn't require any
special maintenance, so to clean it, we will use a chamois. Wooden bridges should be
cleaned the same way as the fingerboards, according to the type of finish.
Cleaning the Electronics
Maintenance of the electronic components mostly consists of
cleaning and lubricating the volume and tone controls. An
aerosol spray designed for cleaning electronic circuits
should be used for this. The most common type is "2-26
Electro" from CRC Industries, which you can find at the
following link http://www.crcindustries.com/ei/. This cleaning
spray prevents the controls from wearing out prematurely.
Depending on the country you live in, you should be able to
find a similar product.

Changing the Strings
Before adjusting the instrument, you should change the strings. This is very important
because, as the strings age, their properties change and the adjustment won't be correct.
Also, if you decide to change the strings later on, all of the adjustments you have done
previously will no longer work and you will have to adjust the instrument again. If you don't
have any new strings, I would advise you to hold off on making the adjustments until you
do.
You should only make adjustments to the instrument if the strings have been on it for less
than a week and if they have been on for less than 4-5 days, it's even better.
With new strings, you assure good intonation and each time you change them, the
instrument will already be correctly adjusted.
Remember that it isn't necessary to take the strings off all at once. It is preferable to
change them one at a time and it doesn't matter if you start with the highest one or the
lowest one.
1. Once you have removed the old string, place the new one across the bridge.
2. Stretch it using the hand furthest away from the tuning head where it will be connected.
3. Cut the string with wire cutters 3-4 inches above the tuning head.
4. Normally, all current tuning heads, whether "Gotoh" or "Schaller," have a hole running
through the center. Thread the string through the hole about ½" to 1" and then begin to
wind the string clockwise with your fingers.
5. You can use the tuning head to help you wind up all of the remaining string until it
begins to tighten.
6. Then, tighten it to the correct tension for that string with the aid of a tuner.
7. Repeat this process with the remaining strings.
8. The number of times you will have to turn the string around the axis of the tuning head
will vary depending on the gauge of the string. The lower strings, such as the B and E

strings, should require 2 or no more than 3 turns. The A and D strings should require 3
or no more than 4 turns and the remaining high strings should require 4 or no more
than 5 turns, except for the very thin, unbraided strings, which will need approximately
6 to 8 turns.
9. Once you have put on all of the strings, retune each one of them to the correct pitch
(see the tuning table here).
Pre-Adjustment of the Bridge - Height
Before adjusting the neck, we have to adjust the approximate height of the strings over the
bridge. If we don't do it at this point, the neck adjustment won't be correct because if the
strings are too close to the bridge or too far away, this will lead to an incorrect estimate of
the true position of the neck.
Bridge Curvature Templates
To adjust the height of the strings, you should use a curvature template. If you don't have
one, you can use the ones included in this Guide. These templates will help you adjust the
bridge to the curvature of the fingerboard. In this way, the strings will be at the correct
distance from it. A bass rarely has a flat fingerboard, although a few more modern
instruments do, such as Barcelona™ or the new Oracle™. The curvature is measured in
inches and can vary considerably, from 7 ½" to 20" or more. The ERB-type multi-string
basses can reach a curvature of 90" and may have a flat fingerboard. The greater the
number of inches, the flatter the fingerboard will be.

Measuring the Curvature of the Fingerboard
First, before adjusting the height of the strings, you have to determine the true curvature of
the fingerboard. If you already know it, you can skip this step.
You will need to remove all of the strings to be able to measure it using the templates
provided in this Guide. Once you know the curvature, you will only need to use the
template that corresponds to your instrument's fingerboard.
Adjusting the Height of the Strings
It is very important that the strings be at a consistent distance from the surface of the
fingerboard (the frets). First, you will need to adjust the height of the two outer strings, that
is, the thinnest and the thickest.

Once you have adjusted the height of the outer strings, adjust the height of the remaining
strings using the template with the same curvature as the fingerboard (Fig. 4). You will
need to cut out all of the templates to determine the true curvature of your instrument's
fingerboard.
Two Types of Templates
There are two types of templates: Type A (Fig. 1) and Type B (Fig. 2). The Type A
templates are slightly more precise because they measure from the underside of the
strings, which prevents any errors resulting from the varying thickness of the strings.
In Fig. 5 you can see that the measuring surfaces are different. In the case of the Type A
template, the measuring surface is from the underside of the strings, but in the case of the
Type B template, the measuring surface is from the exposed side.

Neck Adjustment
The neck adjustment is the most delicate part of the whole process and requires the
highest level of expertise. As I have already mentioned, if you don't have any experience
adjusting your own instrument, practice first on another one that isn't being used. If you
follow all of the instructions that are laid out here, the neck of your instrument will not be at
risk.
Why Does the Neck Have a Truss-Rod and What Does It Do?
If adjusting and tuning your own instrument is all new to you, then you have probably
asked yourself this question more than once.
In general, all basses have a truss-rod, except for those that have a neck made of carbonfiber (we will discuss those necks later on) or those that are very inexpensive.
The truss-rod runs along the inside of the neck across its length from the head stock to the
point where it connects to the body. The truss-rod, itself, may vary, but its function is
always the same: to counterbalance the tension of the strings and hold the neck in the
correct position and shape when it comes to making an optimal adjustment. There are
both fixed and adjustable truss-rods.
Fixed Truss-Rods
The only purpose of fixed truss-rods is to reinforce the neck and these are usually round or
flat steel, titanium, aluminum or carbon-fiber rods. We won't spend a lot of time discussing
this type of truss-rod, since it doesn't allow for making precision adjustments to the neck.
Adjustable Truss-Rods
This type of truss-rod comes in several different formats and can function in several
different ways.

The simplest format is the one used in the basses made by Fender®, for example the Jazz
Bass®, Precision Bass® or the MusicMan® and is basically a round rod approximately
3/16" in diameter.
It is connected to the neck on one side and is threaded with a head on the other side. This
long, threaded screw can be tightened at the head of the truss-rod and is usually slightly
bent inside the channel (Fig. 6).
Neck in a neutral or straight position
Fig. 6
When we loosen the truss-rod, the tension of the strings (red arrow) increases as the
tension of the truss-rod (green arrow) gives way, causing the neck to begin bending
forward (Fig. 7), resulting in a depression in the middle.
The neck begins to bow backwards
By loosening the truss-rod,
we increase its length

Tension of the truss-rod
When we tighten the truss-rod, the tension of the strings (red arrow) is no longer sufficient
to compensate for the tension of the truss-rod (green arrow), causing the neck to bend
backwards (Fig. 8) and rise in the middle.

Now, you will probably ask, "What good does this do? Isn't it good enough to have a
completely straight neck that is strong enough to resist bending no matter which gauge of
strings I'm using?"
Well, here's the point. An optimally adjusted neck shouldn't be straight.
You will discover that the truss-rod doesn't just compensate for the tension of the strings,
but rather it does so in a very precise way, depending on their gauge.
Logic would tell us that once the neck is balanced, it should be completely straight, but in
reality, it doesn't work that way. In Fig. 9, you can see what happens: when a string
vibrates, that vibration reaches its maximum width right in the middle of the string at 1
and a straight neck doesn't leave it enough room, so it begins to hit the neck more or less
at 2

This unwanted effect is commonly called "buzzing" and in order to avoid it, we have to

After raising the strings, the instrument won't buzz 1 , but you will find that it isn't very
comfortable to play, especially in the higher positions 2 . To prevent this problem, you
must slightly arch (Fig. 11) the neck 4 in such a way so that it accommodates the natural
shape of the strings as they vibrate. By doing this, we make sure that the bass doesn't
buzz, so we can then lower the strings at the bridge 3 , achieving a more consistent string
height over the neck 12 , which will give us much more playing comfort all along its
length as opposed to the awkwardness we feel when the neck is completely straight.

How to Measure the Arc
You should always correctly tune the instrument before proceeding. To measure the
current arc of your instrument, you should sit in a comfortable position and support it on
your knee just as if you were going to play it.
Depress the string at the first fret with the index finger of your left hand until it makes
contact (Fig. 11a) and then do the same thing with your right index finger at the last fret on
the neck (Fig. 11b).
Now, observe the string over the 7th through the 9th frets or thereabouts. If the string is
touching all of them, this means that the neck is straight or may even be bent backwards,
as in Fig. 8.
Fig. 11b

0,3 - 1,0 mm
Fig. 11c
If the string doesn't touch the 7th through the 9th frets and there is some distance between
the two, this means that there is an arc. Now, all we have to do is measure this distance to
find out if it is correct.

Fig. 12
To measure the arc, you will need another person to help you or else you will need a capo
(Fig. 12) so that you can hold the strings down at the first fret. You will also need a set of
gauges, as I mentioned in the Tools section of Chapter 1. If you don't have a capo, you
Fig. 13
can improvise using a pencil and a rubber band (Fig. 13).
Place the capo at the first fret so that the strings are touching it. While you are sitting and
holding your instrument as if you were going to play it, hold the string down at the last fret
with your right index finger and use a gauge to measure the distance between the string
and the 7th through the 9th frets. This distance should normally be between .3mm and
1mm, depending on your instrument and playing style. This is not an exact science, but
rather an Art and you will have to experiment a little in order to find the optimal distance
that works for you.
If you don't care so much about having high strings, then this distance can be very slight,
approximately .3mm. If you prefer rather low strings, this distance should be a little
greater. However, it isn't recommended to have a distance greater than 1mm because in
spite of the fact that the bass won't buzz on the first frets, it will start to buzz on the last
ones. On the other hand, if the neck buzzes on the first frets, then we should increase the

indicator we will use to carry out the whole adjustment process.

In Fig. 14 you can see that the bass buzzes at the first frets 1 and stops buzzing more or
less at the middle of the neck 2 and doesn't buzz at all at the last frets 3 , which is a
sign that you need to loosen the truss-rod because the neck isn't arched or it is bowed
back, as you can see in relation to the straight line A-A.

In Fig. 15 the instrument is arched in the correct direction but too much so. The
instrument doesn't buzz at the first frets or in the middle, but it will buzz at the last frets,
which is a sign that the neck should be straightened by tightening the truss-rod. In the
case of most common truss-rods, you will need to tighten the head a quarter-turn
clockwise.
So, now you know the basic mechanics of how the truss-rod works and the
procedures for adjusting it. Next we are going to adjust the neck step by step.

The Neck Adjustment Process
1. As a general rule, the bass should be tuned using standard tuning or whatever tuning
you normally use. Tune it now if you haven't already.
2. Determine the arc of the neck, as described in the previous section.
3. The neck should have a slight arc and the distance between the 7th through the 9th frets
and the underside of the strings should be between .3mm and 1mm.
4. If the arc is greater than this, you need to tighten the truss-rod a quarter-turn clockwise
and if the arc is less than this, you should loosen the truss-rod a quarter-turn
counterclockwise.
5. Remember that most truss-rods work this way; however, in some cases to
tighten them, you have to turn them counterclockwise and to loosen them, you
have to turn them clockwise. Please read the instructions that came with your
instrument very carefully.
6. Tune the instrument again to compensate for the changes you have made to the neck
tension.
7. Test the arc again and if it still isn't within .3mm to 1mm, you will have to repeat the
process as many times as necessary starting from step 4.
8. Remember that you should NEVER tighten or loosen the truss-rod by more than a
quarter-turn at a time. You can even turn it as little as an eighth of a turn if you only
need to make a small adjustment.
9. Once the arc has been adjusted, check the tuning again and try playing the instrument
in all positions to make sure that it doesn't buzz.
10. If it doesn't, you may even be able to lower the strings a bit on the bridge. A half-turn of
the saddle pins should do the trick.
11. Pay attention to where the instrument buzzes. If it does it at the first frets (Fig. 14), you
should loosen the truss-rod a quarter-turn. If it does it at the last frets (Fig. 15), then
you should tighten the truss-rod a quarter-turn.

12. The optimum point is between the place where the bass stops buzzing at the first frets
and the place where it stops buzzing at the last ones.
13. If you can't make it stop buzzing, this means that the strings are too low and you will
need to raise them at the bridge by giving each of the saddle pins a half-turn, as
described in the section Adjusting the Height of the Strings here. You should
readjust the height of the outer strings first and then adjust the height of the others
using the correct curvature template (Fig. 4).
14. You will have to repeat this process of raising the strings on the bridge as many times
as necessary until the bass doesn't buzz at any point along the neck.
15. If the neck buzzes randomly at certain frets, this means that the frets have worn out or
have started to lift up and you will have to turn to a professional luthier to level them.

Bridge – Setting the Intonation
You should know that the distance from the nut to the bridge, which is also called the
"scale length" of the instrument, is the distance between the nut and the 12th fret multiplied
by two (Fig. 16).
As a general rule, the scale length is expressed in inches and the most common one is
34", although this is only in theory because in practice, each of the strings has to be
adjusted slightly in order for the bass to have perfect intonation.
Instrument Scale
half scale
half scale
12th fret
Fig. 16
The 12th fret is located right in the middle of the scale length (neck) of the instrument
Setting the intonation is the process of correcting the length of the strings so that the bass
is perfectly in tune at every position (fret).
Due to the different thicknesses of the strings, the elasticity of each one changes, which
means that the strings with less elasticity won't be perfectly in tune in all positions because
this loss of elasticity causes the effective length of the strings (the part that vibrates) to be
shorter than the distance between the nut and the bridge.
The thicker a string is, the more elasticity it loses and we have to compensate more and
more by moving the saddle of the bridge further from the theoretical "scale length" of the
instrument, which you will observe in an instrument that has been adjusted correctly.
You will see that the saddles have a repeating adjustment pattern: the thicker the string is,
the longer it has to be in order to compensate for this elasticity problem (Fig. 16).

The Intonation Setting Process
The procedure is very simple. To compensate for the elasticity problem, we have to move
the saddle of the bridge until the harmonic of the 12th fret coincides with the pitch of the
12th fret. In this way, we will synchronize the distances of the frets with the actual pitches
of the string.
1. Check the tuning again and begin setting the intonation starting with the thinnest string.
2. Place the tip of your left index finger on the 12th fret, touching the string lightly without
pressing it all the way down (as if you were trying to stop the string from vibrating) and
strum the string with one of the fingers of your right hand to produce the harmonic of
the 12th fret.
3. While the harmonic is still sounding, tune the string to its correct pitch. For example, if
it's the G string, tune it to G.

4. Now, play the pitch of the 12th fret (not the harmonic) by pressing the string all the way
against the fret.
5. If the note is higher (Fig. 17), you need to move the saddle away from the pickups
toward the outside of the body.
6. If the note is lower (Fig. 18), you need to move the saddle closer to the pickups.
7. The more difference there is between the harmonic of the string and the correct pitch,
the more we have to move the saddle to compensate for this difference.
8. You should repeat this process as many times as necessary until the pitch at the 12th
fret coincides with its harmonic. In this case, the tuner should indicate the correct pitch
in the middle (Fig. 19).
9. Repeat this same process with each string.

The higher the pitch at the 12th fret in relation to the harmonic, the more you will have to move the
saddle outward and away from the pickups to lengthen the string. Move the saddle away from the
pickups if the note is higher than the harmonic.

Adjusting the Height and Angle of the Pickups
A very important point that we often overlook is the adjustment of the height of the pickups.
Basically, adjusting the height of the pickups is necessary to accommodate the different
volumes that are produced depending on their position. The pickup closest to the
fingerboard and furthest from the bridge produces a higher volume than the pickup closest
to the bridge. This is because of the change in the width of the string's vibration (Fig. 20).
This adjustment also helps accommodate the differences in volume between the thinner
and thicker strings (Fig. 22) and lastly, it helps prevent the pickups from grating against
any strings that are too close to them.
The wider the vibration, the higher
the volume
The narrower the vibration, the
lower the volume

The Adjustment Process
1. Place the instrument on a flat surface.
2. Press the lowest string against the last fret with your left index finger (Fig. 21).
3. Using the gauges, adjust the distance between the string and the surface of the higher
pickup to somewhere between 1.5mm and 2.5mm and for the lower pickup, between
2mm and 3mm.
4. Repeat the same process with the highest string.

volume between the strings (Fig. 22).

Lastly, if the pickups of your bass have more than 2 mounting screws, like those of the
MusicMan® bass, which have 3 or the JazzBass®, which have 4, you will need to adjust
the surface of the pickup so that it is parallel to the central axis of the string (Fig. 23).

The Adjustment Schedule
Routine adjustment of the instrument, which includes adjusting the truss-rod, the bridge
and the height of the pickups, that is, everything we have discussed so far, should be done
every 6 to 12 months. The reason why this period can vary so widely is because some
instruments fall out of adjustment much more quickly than others due to the design of the
bridge and the structure of the neck.
Check the status of your instrument every 6 months. If you find that the adjustment has
hardly changed and the neck is still stable, then you can wait 12 months between routine
adjustments.

Instruments with a Double Truss-Rod
Instruments with two truss-rods are not at all rare these days. There are several
manufacturers that use this type of system, especially in the ERB-type basses, which
require a somewhat independent adjustment at the two extremes of their unusually
wide fingerboards.
There are some manufacturers that use this
system in conventional basses and have done
so for many years, as is the case with
Rickenbacker basses, the old Tobias basses or
the Alembic basses.
Basically, there are two kinds of double trussrod systems used in basses:
1. Parallel truss-rods that are joined
together inside the middle of the neck
2. Diagonal and parallel truss-rods at
each edge of the fingerboard
Parallel Truss-Rod System (A+A)
This system differs very little from the
conventional single truss-rod system. The two
truss-rods must have the same tension and
that's about all there is to it. If you have a bass
with this system, study the previous chapter on
adjusting a bass with a single truss-rod again
and follow the instructions just the same, the
Tip #5
In basses with two parallel
truss-rods, whenever possible,
use a torque wrench. This is a
type of hand tool that is used
to tighten screws that require
very precise adjustments due
to their function. This will
allow you to apply the same
tension consistently to the two
truss-rods in this kind of
system.

only difference being that you will need to make sure that both truss-rods are set at the
same tension, which requires a little more experience and a lot of caution.
two parallel truss-rods A+A
Diagram of an instrument with a parallel truss-rod system A+A
The premise is always the same: it's better to under-tighten than to over-tighten. To make
adjusting this kind of instrument easier and to prevent damaging it, I suggest that you use
a torque wrench (see Tip #5) whenever possible.
Diagonal Double Truss-Rod System (A+B)
The situation starts to get complicated and confusing when there is a diagonal truss-rod
system.
In this case, the adjustment doesn't seem quite as simple as it is with the parallel trussrods that are side by side. In reality, and this is the paradox, the diagonal double truss-rod
system is much easier to adjust than the parallel double truss-rod system! Strange, isn't
it?
First, let me explain the reason for this kind of system and the idea behind it. This will help
you understand how it works and afterwards, the adjustment will seem easy – no more
complicated than adjusting a neck with a single truss-rod.

The Ultimate Guide to The Perfect Bass Setup
version 1.0
The Philosophy of the System
The idea behind this system is very simple. You already know from the previous chapter
that the neck needs to have a slight arc so that the strings are kept at an optimum height
over the fingerboard.
This arc isn't the same for all of the strings because it varies slightly according to their
thickness. This is due to the width of the string's vibration.
The strings of the highest gauge have a wider vibration than the thinner strings, so these
thicker strings require a more pronounced arc while the thinner ones require a less
pronounced arc.
When we're talking about basses with 4, 5 or even 6 strings, this difference in arc isn't very
big and a truss-rod located along the central axis of the neck is sufficient. Things get more
complicated in multi-string instruments of the ERB (Extended Range Bass) type.
These basses with 7, 8, 9 or up to 12 strings have extremely wide fingerboards and the
gauge of the strings varies widely, which makes it necessary to apply a different arc at
each edge of the fingerboard, which is made possible by the diagonal truss-rod system.
You should also know that once the strings are tuned to the correct pitch, they have
different tensions. But we already know this, right?
However, what most people don't know is that the strings with the greatest tension are the
thin ones and not the thick ones, as logic might suggest.
This puts more stress on the neck from the high strings and less stress from the low ones.
Going back to the arc, if we have to apply less curvature on the side where the high strings
are located and more on the side where the low strings are located, we will notice that the
truss-rod that has to withstand the most stress is truss-rod "A."
So, now that we know this, how should we adjust the neck with a diagonal double trussrod (A+B)?

It's Really Very Simple!
Treat it as if it were a bass with a single truss-rod, adjusting only truss-rod "A". Truss-rod
"B" will only be used, then, to compensate in case the arc of the top edge is too
pronounced or curved.
Here's the Complete Procedure:
1) Loosen truss-rod "B" completely so that there's no tension at all.
2) Tune the instrument again to compensate for the reduced neck tension.
3) Check the arc of the neck at the lower edge of the highest string, just as we did in the
previous chapter.
4) If the neck is too bowed, tighten truss-rod "A" by a quarter-turn.
5) If the neck isn't bowed enough, loosen truss-rod "A" by a quarter-turn.
6) Tune the instrument again to compensate for the change in neck tension.
7) Repeat the process starting at step 3 until the lower edge has the correct arc.

8) Tighten truss-rod "B," if necessary, so that the top edge has the correct arc. In most
cases, this won't be necessary and you will only have to tighten it minimally so that the
head of the truss-rod isn't completely loose.
9) If it is necessary to decrease the arc of the top edge of the fingerboard, you will have to
tighten truss-rod "B" by an eighth of a turn.
10) Tune the instrument again to compensate for the increased neck tension.
11) Check the resulting arc again after having tightened truss-rod "B" and if it still isn't
right, repeat the process starting at step 8 until it is.
12) If you have had to tighten truss-rod "B" a bit, once you have done this, check the arc at
the bottom edge of the fingerboard again and if necessary, tighten or loosen truss-rod
"A" to compensate.
