Introduction
Congratulations on your purchase of the Rocktron VersaTune Rack Tuner.
The VersaTune Rack Tuner is a versatile true-bypass Guitar/Bass rack tuner for live and studio use. The
large “NOTE” display and bright LEDs provide the perfect amount of light for on-stage tuning. Over a
hundred different tunings can be viewed in the display window including standard guitar/bass tunings,
alternate tunings, drop tunings and opening tunings. Additional features include two front & rear panel
inputs, two rear panel outputs, input selector switch, +-60 Cents tuning LEDs, Precision Switch for ultra fine tuning, strobe, Mute Switch on front panel and MUTE jack on rear panel, Calibration switch and
NOTE selection switch.
Want to tune your guitar a half step down? Wanted to tune your guitar to DADGAD? Need to tune a
Mandolin, Dobro, Pedal Steel Guitar or other types of instruments? Well, the VersaTune can help you to
adjust to these tunings. The VersaTune tunings display window shows you how! Up () and down ()
arrows appear in the display window next to the note to show “how” to tune to a particular tuning from
standard A440 tuning. For example, to tune a guitar down a half step from standard A440, the window
will show a “down” () arrow next to the note you are tuning down to. Start by tuning the low E string
down to D# or Eb as the window will show “down arrow” D#, (meaning to tune that string down to D#
or Eb) . Continue with the same process for other strings.
Use the Up/Down buttons to select different tunings from standard guitar and bass tunings to a wide range
of alternate tunings and tunings for different types of instruments. Additional tunings for 7-String Guitar,
5-String and 6-String bass are included. Tunings for other instruments such as dobro, mandolin family,
banjo, pedal steel, classical instruments and other string instruments (Bouzouki, Banduria, Dulcimer, Requinto, etc) are also included.
Let your creative juices flow and try some of these different tunings!

16
TUNING LEDS SHARP/FLAT LEDS - When the note being played is IN TUNE the GREEN LED in the
center of the LED panel will light. The RED LEDs show you if your note is Sharp or Flat. RED LEDs to the
right of the GREEN LED are sharp and the string should be tuned down. The farther right the LED is away
from the GREEN IN TUNE LED the more the note is SHARP. RED LEDs to the left of the GREEN LED are
flat and the string should be tuned up. The farther left the LED is away from the GREEN IN TUNE LED the
more the note is flat. In PRECISION MODE the LEDs are opposite. The IN TUNE LED will be RED and the out of tune LEDs
are GREEN. The GREEN LEDs show you if your note is Sharp or Flat. GREEN LEDs to the right of the
RED LED are sharp and the string should be tuned down. The farther right the LED is away from the RED
IN TUNE LED the more the note is SHARP. GREEN LEDs to the left of the RED LED are flat and the string
should be tuned up. The farther left the LED is away from the RED IN TUNE LED the more the note is flat.

Using the VersaTune
STANDARD TUNING MODE
In Standard Tuning Mode (this is the default tuning mode when you turn on the VersaTune) the LEDs on the front
panel will indicate the following:
GREEN LED - Center LED with the (0 - zero) above the LED will indicate that the note being played is “IN TUNE”
RED LEDs - To the left of the GREEN center LED will indicate that note being played is “FLAT”. The numbers
shown on the front panel -10, -20, -30, - 40 indicate by how many “CENTS” the note being played is off from being
IN TUNE.
RED LEDs - To the right of the GREEN center LED will indicate that the note being played is “SHARP” from being
IN TUNE. The numbers on the front panel +10, +20, +30, +40 indicate by how many “CENTS” the note being played
is off from being IN TUNE.
CENTS - The Cent is a logarithmic unit of measure used to musical intervals. Twelve-tone equal temperament divides an octave into 12 semi tones of 100 cents each. Cents are used to measure extremely small finite intervals or to compare the sizes of comparable intervals in different tuning systems. Usually the interval of once cent is to small to be heard between successive notes.
Step 1 - plug the guitar/bass into Jack 1 or 2 of the Tuner and using the input select button select the appropriate jack
(CH1 or CH2).
Step 2 - play a note on your guitar. Pluck your E string, if needed, adjust your tuning machine on your instrument
until the letter “E” appears in the NOTE Display window.
Step 3 - if your note is flat - the “FLAT” LEDs to the left of the IN TUNE GREEN LED will light. The farther away
the RED LED is from the GREEN IN TUNE LED the more flat the tuning is. If a Flat LED is lit, tune your string up.
During this process the LEDs will begin to light and move closer to the GREEN IN TUNE LED.
Step 4 - if your note is sharp - the “SHARP” LEDs to the right of the IN TUNE GREEN LEDs will light. The farther
away the RED LED is from the GREEN IN TUNE LED the more sharp the tuning is. If a sharp LED is lit, tune your
string down. During this process the LEDs will begin to light and move closer to the GREEN IN TUNE LED.
Step 5 - Continue with step 3 or step 4 until the flat or sharp LEDs are not lit and the GREEN “IN TUNE” LED lights.
At this point the string is IN TUNE.
Step 6 - Continue steps 2-5 but using your other strings on your guitar or bass.
Using the VersaTune
PRECISION TUNING MODE
Precision Tuning Mode allows you to “FINE” tune your instrument. This function increases the sensitivity of
the VersaTune to allow for ultra fine tuning. In Precision Tuning Mode, the LEDs are reversed in color. Now
the IN TUNE LED will be RED and the Flat and Sharp LEDs will be GREEN. This mode is quite sensitive and
very slightly movements of the tuning machines on your instrument is necessary.
RED LED - Center LED with the (0 - zero) above the LED will indicate that the note being played is “IN
TUNE”
GREEN LEDs - To the left of the RED center LED will indicate that note being played is “FLAT”. The numbers shown on the front panel -1, -2, -3, - 4 indicate by how many “CENTS” the note being played is off from
being IN TUNE.
GREEN LEDs - To the right of the RED center LED will indicate that the note being played is “SHARP” from
being IN TUNE. The numbers on the front panel +1, +2, +3, +4 indicate by how many “CENTS” the note being
played is off from being IN TUNE.
These steps are similar to the Standard Tuning Mode steps, but require more slight adjustments to your tuning machines on your instrument.
Step 1 - plug the guitar/bass into Jack 1 or 2 of the Tuner and using the input select button select the appropriate
jack (CH1 or CH2).
Step 2 - play a note on your guitar. Pluck your E string, if needed, adjust your tuning machine on your instrument until the letter “E” appears in the NOTE Display window.
Step 3 - if your note is flat - the “FLAT” LEDs to the left of the IN TUNE RED LED will light. The farther
away the GREEN LED is from the RED IN TUNE LED the more flat the tuning is. If a Flat LED is lit, tune
your string up. During this process the LEDs will begin to light and move closer to the RED IN TUNE LED.
Step 4 - if your note is sharp - the “SHARP” LEDs to the right of the IN TUNE RED LEDs will light. The farther away the GREEN LED is from the RED IN TUNE LED the more sharp the tuning is. If a sharp LED is lit,
tune your string down. During this process the LEDs will begin to light and move closer to the RED IN TUNE
LED.
Step 5 - Continue with step 3 or step 4 until the flat or sharp LEDs are not lit and the RED “IN TUNE” LED
lights. At this point the string is IN TUNE.
Step 6 - Continue steps 2-5 but using your other strings on your guitar or bass.
Using the VersaTune
STROBE TUNING MODE
The STROBE function of the VersaTune is very sensitive.
Step 1 - plug the guitar/bass into the tuner and press the “STROBE” button. At this point the RED LEDs will appear
to move from right to left.
Step 2 - play a note on your guitar. Pluck your E string, if needed, adjust your tuning machine on your instrument
until the letter “E” appears in the NOTE Display window.
Step 3 - if your note is flat - the RED LEDs will appear to be moving from right to left, showing you that the note being played is flat. The faster the LEDs move right to left, the more flat the tuning is. Tune your string up. During this
process the speed of the movement of the LEDs will appear to slow down as you approach being IN TUNE. When the
LEDs don’t appear to be moving, then the note is IN TUNE.
Step 4 - if your note is sharp - the RED LEDs will appear to be moving from left to right, showing you that the note
being played is sharp. The faster the LEDs move from left to right, the more sharp the tuning is. Tune your string
down. During this process the speed of the movement of the LEDs will appear to slow down as you approach being
IN TUNE. When the LEDs don’t appear to be moving, then the note is IN TUNE.
HINTS AND TIPS
The VersaTune is sensitive, so it is not necessary to strike your string very hard. Standard string attack will work. Additionally, if you are in a loud environment try using harmonics to tune your instrument. Lightly touch the string over the 12th fret of your instrument and pick the string with normal
pick attack. This will create a harmonic. It will work on all strings. The MUTED Output is ideal for
tuning in live situations. This allows you to tune without everyone in the audience hearing you tune.
Additionally, this will mute the signal going to your amplifier which will help you keep down noise
generated if you are using a high gain amplifier.
Using the VersaTune
CALIBRATION
A440Hz is the musical note A above middle C. It has a frequency of 440Hz and is the general tuning standard
for musical pitch. It is sometimes referred to as Concert A.
Occasionally there is a need to tune slightly off A440 pitch and this is where the CALIBRATION function comes
in handy. You can adjust the VersaTune up and down slightly in the pitch that it reads so that the IN TUNE LED
will light when you are IN TUNE with that change in pitch.
You can calibrate the VersaTune to different pitches to help you tune to the pitch of instrument or audio source that
may not be in tune to A440 pitch (like an old piano or tape player). When you press the CALIBRATION button,
the NOTE display window will 0 - 9 numbers, the code list is as follows:
NOTE DISPLAY WINDOW

9 439Hz
Steps to Calibrate the VersaTune:
Step 1 - press the “CALIBRATION” Button on the front panel. The “NOTE” display window will show “0” (Zero) in the window. This is the indication that the calibration of the VersaTune is set to standard A440 tuning. If you do nothing at this point, the “0” will flash after a few seconds and disappear. This means that the VersaTune is still set to A440 Tuning. Step 2 - Press the “CALIBRATION” Button a second time and you will see a “1” - (ONE) in the NOTE display
window. The “1” will flash after a few seconds and disappear. This indicates that the VersaTune is now calibrated
to A441Hz . To check this press the CALIBRATION button again and you will see a “1” in the note display window.
Step 3 - Press the “CALIBRATION” Button a third time and you will see a “2” - (TWO) in the NOTE display
window. The “2” will flash after a few seconds and disappear. This indicates that the VersaTune is now calibrated
to A441Hz . To check this press the CALIBRATION button again and you will see a “2” in the note display window. This indicates that the VersaTune is now calibrated to A442Hz.
Step 4 - To access other calibrations follow above steps to further adjust the VersaTune.
NOTE: At any time you can return the VersaTune’s pitch to A440 by “PRESS AND HOLD” the CALIBRATION
button and the calibration until the “0” (Zero) appears in the NOTE DISPLAY WINDOW. The “0” will flash and
the VersaTune has returned to A440 calibration.
TUNINGS WINDOW
A unique feature on the VersaTune is the “TUNINGS WINDOW”. The TUNINGS WINDOW shows over a hundred
different of tunings and how to tune to these tunings from the standard A440 Guitar Tuning. Additionally, we have
included some other tunings for different instruments such as, mandolin, mandola, pedal steel, banjo and many others. Use the UP & DOWN buttons on the front panel to scroll through the different tunings.
TUNINGS WINDOW LAYOUT
The tunings of strings goes from left to right and are from Low String to High String. Thus in this window “1:Guitar Standard Tuning: E A D G B E your guitar should be tuned as follows:
6th string (lowest string) - tuned to “E”
5th string (next higher string) - tuned to “A”
4th string (next higher string) - tuned to “D”
3rd string (next higher string) - tuned to “G”
2nd string (next higher string) - tuned to “B”
1st string (next higher string) - tuned to “E”
ALTERNATE TUNINGS
Follow these steps to tune your guitar to most of these tunings:
Step 1 - Tune your guitar to standard A440 tuning (it is 1:Guitar Standard) in the TUNINGS WINDOW.
Step 2 - Us the “UP” button to select (2: Guitar Drop D) in the TUNINGS WINDOW.
You will notice that the “D” in the window has a () - DOWN ARROW - next to it. This means you should
tune your low E string DOWN to D.
TUNINGS WINDOW....CONTINUED....
Here is a slightly more involved tuning. Use the UP & DOWN buttons on the front panel to select 1: Guitar Standard in the TUNINGS WINDOW.
Step 1 - Tune your guitar to standard A440 tuning (it is 1:Guitar Standard) in the TUNINGS WINDOW.
Step 2 - Us the “UP” button to select (3: Guitar 1/2 Step Down) in the TUNINGS WINDOW.
You will notice that the all notes have a () - DOWN ARROW - next to it. This means you should tune
all of your strings down to these notes.
6th string (lowest string) E down to D#
5th string (next higher string) A down to G#
4th string (next higher string) D down to C#
3rd string (next higher string) G down to F#
2nd string (next higher string) B down to A#
1st string (next higher string) E down to D#
Note: Usually, when you tune a guitar down a 1/2 step it is often called “tuning a half step down” or “tuning to
Eb”. However, as the industry standard tuners appear use the “SHARP” “#” indicator as the main way to determine the half steps between notes, the VersaTune in Standard mode also uses the “SHARP” “#” indicator. Thus,
in the TUNINGS WINDOW, when tuning a guitar a half step down, instead of the note reading Eb, the note will
read D#, which is the same note.
