CARE AND MAINTENANCE
Congratulations on your purchase of the
YAMAHA electric guitar.
With reasonable care, your YAMAHA electric
guitar will age gracefully and provide many
years of superlative musical service.
* When connecting or disconnecting cables, turn off the ampli-
fier and other equipment or reduce the volume.
* After playing, wipe the entire guitar down, including strings,
with a good polishing cloth. This will remove corrosive skin
oils and acids, and protect the plating, finish, and strings.
* Avoid exposing the guitar to direct sunlight and extremes of
heat and humidity.

TUNING MACHINE TENSION ADJUSTMENT HEIGHT ADJUSTABLE LOCKING NUT
The tuning machines have spring-loaded mechanisms which
automatically take up wear, preventing backlash. However, it is
possible to adjust the amount of pressure required to turn the
machines. Each machine has a tension adjustment screw, as
illustrated.
1) Remove 3 pcs. of hexagonal screws fixing the Lock Pads.
(illustration — A)
2) Loosen 4 pcs. of screws fixing the Nut Base.
(illustration — B)
3) Adjust the height by the Height Adjustment Screw. The Nut
Base gets higher by clockwise rotation, and lower by coun-
terclockwise rotation. (illustration — C)
Clockwise screw rotation tightens the machine. The tuning ma-
chines should be adjusted to the extent that they are firm, but
can turn smoothly. This adjustment is normally unnecessary,
and excessive tightening can lead to premature tuning machine
wear.
NOTE:As the height has been adjusted in the best condi-
tion in the factory, please avoid the adjustment
unless you have suitable experience. We suggest
that you entrust this adjustment to your dealer.

SETTING THE STRING ACTION
— Bridge —
NOTE:Be sure to perform any necessary adjustments to the
truss rod before performing the following adjustments.
Set one end of the 15 cm rule on top of the last fret with the flat
side of the rule against the string and measure the space be-
tween the top of the last fret and bottom of 1st string, 6th string.
The recommended height for each string should be as follows:
• 1st string: 1.9 ±0.2 mm
• 6th string: 2.4 ±0.2 mm

VIBRATO SYSTEM Vintage Type
Following is the procedure for adjusting the vintage vibrato
system: To check intonation, compare the harmonic tone (12th fret) to the fretted tone (12th fret).
●If fretted pitch is higher than harmonic, saddle must be moved
backward to lengthen string.
●If fretted pitch is lower than harmonic, saddle must be moved
forward to shorten string.

VIBRATO SYSTEM TRS-PRO/101 (part 1)
When changing strings it is necessary to cut off the ball ends of
the strings.
Following is the procedure for changing strings and adjusting
the vibrato system:
1) Using the supplied hexagonal wrench, loosen the three hex-
agonal screws on the lock above the nut. (illustration — A)
2) Loosen the individual string locks using the supplied hex-
agonal wrench. (illustration — B)
3) Replace the old strings with new strings.
4) Using the hexagonal wrench, lock each string.
(illustration — B)
After locking the strings, make sure that the fine tuning
thumb screws are in the middle of their range of travel.
(illustration — C)
5) Tune the guitar to the correct pitch.
6) Remove the back plate to gain access to the vibrato strings.
Three springs are factory installed and we recommend that
these springs be adjusted so that the vibrato bridge plate is
parallel to the top of the guitar when it is tuned to correct
pitch.
7) Lock the strings above the nut. (illustration — A)
8) Use the fine tuning thumb screw to tune the guitar to the
correct pitch. (illustration — C)

stationary. (illustration — D)

YAMAHA ORIGINAL DESIGN VIBRATO SYSTEM RM - Pro II /III (part 1)
The strings are top-loaded from the rear of the bridge and it is not
necessary to cut off the ball end as on other vibrato systems.
Following is the procedure for changing strings and adjusting the
vibrato system:
1) Loosen the three hexagonal screws on the lock above the nut.
(illustration — A)
2) Loosen the individual string locks using the hexagonal wrench.
(illustration — B)
3) Replace the old strings with new strings and tune the guitar to

Intonation Adjustment in Vibrato Bridge
1) Loosen the hexagonal screw located in front of each saddle
using the supplied hexagonal wrench. (illustration — D)
2) Use the hexagonal wrench to adjust the individual string
lengths. These screws are located directly below the string
mounting holes. (illustration — F)
3) When the intonation is correct, tighten the hexagonal screw
in front of each saddle to ensure that its position stays
stationary. (illustration — D)
Tension Adjustment in Vibrato Arm
Adjust the tension rotating the Arm Collar. (illustration — E)
Removing the Vibrato Arm
When you pop in/out the Vibrato Arm, please be sure to
loosen the Arm Collar first, and then pop in/out the Vibrato
Arm.

BRIDGE/SPRING TENSION ADJUSTMENTS
For best results the bridge should always be adjusted so it is
parallel to the top surface of the guitar as shown in illustration
(below). This position is maintained by opposing tension be-
tween the strings and the claw springs. If you change string
gauge, you will need to readjust the spring tension to return the
bridge back to the parallel position.
The adjustment procedures are:
1) Remove the screws that attach the tremolo cavity back plate
from the back side of the guitar exposing the claw springs.
2) Make sure that the guitar is tuned to proper pitch.
3) If the bridge is tilted forward (up), tighten spring tension by
turning the claw screws clockwise. If the bridge is tilted back
(down), loosen the spring tension by turning the claw screws
counterclockwise.
(illustration — A)
Be sure to check string pitch after each adjustment to the
spring tension.
