The following setup procedures and specifications for your
Fender bass were derived using the strings, which come on the
instruments as standard equipment from the factory. Note:
If you plan to change string gauges, you may need to
adjust the specs somewhat to compensate for the changes in
string sizes. Modifications of the specifications may also be
made, (within limited parameters) to adjust for your
individual playing style or application (i.e., how hard you
pick, finger, slap, pop, or fret the bass) Note:
These are minimum specifications, which are meant to guide
you, and should not to be taken as hard and fast rules, as we
realize that every player's subjective requirements may differ
somewhat.

Strings
New bass strings can breathe new life into your bass. A lot
of the thump and pop you expect from your bass starts right
here. In order for strings to stay in tune well, they should
be changed on a regular basis. Strings that have lost their
integrity (worn where the string is pressed against the fret)
or have become oxidized, rusty, and dirty will not return to
pitch properly. To check if your strings need changing, run a
finger underneath the string and feel for dirt, rust or flat
spots. If you find any of these, you should change your
strings.
Fender offers a variety of bass strings -- from the smooth,
vintage sounding, pure nickel Original Bass 7150's, the
pumpin' response of the Super Bass 7250's, to the bright,
snappy performance of the Stainless Steel 7350's. There are
choices of long scale, medium scale, or short scale; strings
that are taperwound, and strings that are designed for either
top loading or a string-through-the-body bridge designs.
Whatever your need -- to fit your bass -- these strings will
give you the jump-start you need.
Because of the amount of tension prevalent on the neck, it
is advisable to replace and tune each new string before
removing the next string. After the whole set is changed and
tuned; make sure that you stretch your strings properly. This
is done by holding the strings at the first fret and hooking
your fingers under each string (one at a time) and then
tugging lightly, moving your hand from the bridge to the neck.
Re-tune and repeat this procedure several times.

Tuning Keys
Whether your bass has standard or vintage tuning keys; how
you wind the strings onto the pegs is very important. First
start by loading each string through the bridge and then
loading it onto the appropriate key as follows:
Standard keys - You will want to pre-cut each string
to achieve the proper length and the desired amount of winds.
Pull the 4th string 3" (76 mm) past the 4th string tuning post
and cut it (make sure when you are pulling the strings that
you are pulling the string taut). Insert through the eyelet in
the tuning key, allowing approximately 1/16" (1.6 mm) of the
end to extend through the eyelet, then wind neatly in a
downward pattern (carefully as to prevent overlapping of the
strings). Pull the 3rd string 3 1//2" (89 mm) past the 3rd
string tuning post and cut it. Now, repeat the winding
procedure. Pull the 2nd string 3 1/2" (89 mm) past the 2nd
string tuning post and cut it. Again, repeat the winding
procedure. Pull the 1st string 3 1/2" (89 mm) past the 1st
string tuning post and cut it. Finally, repeat the winding
procedure one more time. Note: For 5-string basses
follow the above procedures, cutting the 5th string 3" (76 mm)
past the 5th tuning post.
Vintage keys - You will want to pre-cut each string
to achieve the proper length and the desired amount of winds.
Pull the 4th string 4" (102 mm) past the 4th string tuning
post and cut it (make sure when you are pulling the strings
that you are pulling the string taut). Insert into the center
hole of the tuning key, bend and crimp to a 90° angle, and
wind neatly in a downward pattern (carefully as to prevent
overlapping of the strings). Pull the 3rd string 4 1/2" (114
mm) past the 3rd string tuning post and cut it. Now, repeat
the winding procedure. Pull the 2nd string 4 1/2" (114 mm)
past the 2nd string tuning post and cut it. Again, repeat the
winding procedure. Pull the 1st string 4 1/2" (114 mm) past
the 1st string tuning post and cut it. Finally, repeat the
winding procedure one more time. Note: For 5-string
basses follow the above procedure cutting the 5th string 3
1/2" (89 mm) past the 5th tuning post.
Intonation (Roughing it out)
You can pre-set the basic intonation of your bass by taking
your tape measure and measuring from the inside of the nut to
the center of the 12th fret (the wire, not the
fingerboard). Double that measurement to find the scale
length of your bass. Adjust the 1st string bridge saddle to
this scale length, measuring from the inside of the nut to the
center of the bridge saddle. Now, adjust the distance of the
2nd saddle back from the 1st saddle, using the gauge of the
2nd string as a measurement (Example: If the 2nd string is
.060" (1.5 mm) you would move the 2nd string back .060"
(1.5 mm) from the 1st saddle). Move the 3rd back
from the 2nd saddle, using the gauge of the 3rd string as a
measurement. The 4th in the same method (and 5th if you have a
5-string bass). Note: If you are using
taperwound 4th string (and 5th if you have a 5-string bass)
use the actual gauge of the string for your measurement-not
the dimension of the tapered portion of the string.
Truss-Rod
Check your tuning. Install a capo at the 1st fret, depress
the 4th string at the last fret. With a feeler gauge, check
the gap between the bottom of the string and the top of the
8th fret -- see the specification chart below for the proper
gap. Caution: Because of the amount of string tension
placed on the neck (some basses also feature graphite
reinforced necks, adding to the resistance present while the
bass is tuned to pitch), it is advisable to loosen the strings
prior to making any actual adjustment. After the adjustment is
made retune the strings to pitch and recheck the gap with the
feeler gauge.
Adjustment At Headstock (Allen wrench): Sight down
the edge of the fingerboard from behind the headstock, looking
toward the body of the instrument. If neck is too concave
(action too high), turn the truss rod nut clock-wise to remove
excess relief. If the neck is too convex (strings too close to
the fingerboard), turn the truss rod nut counter-clockwise to
allow the string tension to pull more relief into the neck.
Check your tuning, then recheck the gap with the feeler gauge
and re-adjust as needed.
Adjustment At Neck Joint (Phillips screwdriver or Allen
wrench): Sight down the edge of the fingerboard from
behind the body, looking up toward the headstock of the
instrument. If the neck is too concave (action too high), turn
the truss rod nut clock-wise to remove excess relief. If the
neck is too convex (strings too close to the fingerboard),
turn the truss rod nut counter-clockwise to allow the string
tension to pull more relief into the neck. Check your tuning,
then recheck the gap with the feeler gauge and re-adjust as
needed.
Note: In either case, if you meet excessive resistance when
adjusting the truss rod, your instrument needs constant
adjustment, adjusting the truss rod has no effect on the neck,
or you're simply not comfortable making this type of
adjustment yourself, take your instrument to your local
Authorized Fender
Service Center.

Action
Players with a light touch can get away with lower action,
others need higher action to avoid rattles. Check tuning.
Using the 6" (150 mm) ruler, measure distance between bottom
of strings and top of the 17th fret. Adjust bridge saddles to
the height according to the chart, then re-tune. Experiment
with the height until the desired sound and feel is
achieved.

Shimming/Micro-Tilt Adjustment
Shimming is a procedure used to adjust the pitch of the
neck in relation to the body. A shim is placed in the neck
pocket, underneath the butt-end of the neck. On many of the
American series guitars, a Micro-Tilt adjustment is offered.
It replaces the need for a shim by using a hex screw against a
plate installed in the butt-end of the neck. The need to
adjust the pitch (raising the butt-end of the neck in the
pocket, thereby pitching the neck back) of the neck occurs in
situations where the string height is high and the action
adjustment is as low as the adjustment will allow.
To properly shim a neck the neck needs to be removed from
the neck pocket of the body. A shim approximately 1/4" (6.4
mm) wide x 1 3/4" (44.5 mm) long x .010" (0.25 mm) thick will
allow you to raise the action approximately 1/32" (0.8 mm).
For those guitars with the Micro-Tilt adjustment, loosen the
two neck screws on both sides of the adjustment access hole on
the neckplate by at least 4 full turns. Tightening the hex
adjustment screw with an 1/8" hex wrench approximately 1/4
turn will allow you to raise the action approximately 1/32"
(0.8 mm). Retighten the neck screws when the adjustment is
complete. The pitch of the neck on your guitar has been preset
at the factory and in most cases will not need to be adjusted.
Note: If you feel you need this adjustment to be made and
you're not comfortable with the procedure, take your guitar to
your authorized Fender
Service Center.
Pickups
Setting pickups too high can cause a number of unusual
occurrences. Depress strings at last fret. Using 6" (150 mm)
ruler, measure the distance from the bottom of the 1st and 4th
strings to top of the pole piece. Rule of thumb--distance
should be greatest at the 4th string neck pickup and closest
at the 1st string bridge position. Follow the measurement
guidelines from the chart as starting points. The distance
will vary according to the amount of magnetic pull of the
pickup. Note: Larger gauges of strings need wider
vibrational allowances. If you have a 5-string bass or are
using a heavier gauge of string, your measurements will need
to be increased accordingly.

Intonation (Fine Tuning)
Final intonation
adjustments should be made after all of the above have been
finished. Set the pickup selector in the middle, volume and
tone controls to the max. Check tuning. Compare each string at
the 12th fret harmonic to fretted note. If sharp, lengthen
string by adjusting the saddle back. If flat, shorten string
by moving the saddle forward. Remember basses are tempered
instruments, retune, play and make further adjustments as
needed.
Additional Hints
There are a couple of
additional things that you can do to optimize your tuning
stability that have more to do with playing and tuning habits.
Each time that you go to play your bass, before you do your
final tuning, play for a few minutes to allow the strings to
warm-up. Metal expands when warm and contracts when cool.
After you have played a few riffs, done a few slaps and pops,
you can then do your final tuning. Remember that with most
tuning keys it's desirable to tune up to pitch. However, with
locking tuners go past the note, and tune down to pitch.
Finally, wipe strings, neck, and bridge with a lint free
clothe after playing. When transporting or storing your bass,
even for short periods, avoid leaving it anyplace you wouldn't
feel comfortable yourself.
