Introduction
Congratulations on your purchase of the Rocktron
X-Tune.
The X-Tune provides easy tuning in a cool pedal
format. A chromatic pedal tuner for guitar and bass, the

it easy to tune on dark stages. Built in Rocktron’s
strong aluminum chassis, the X-Tune allows muting for
silent tuning, and continuous out for live tuning. The
X-Tune handles 12 Note tuning and a 7 octave range. A
calibration switch is provided. Like most Rocktron
pedals, the X-Tune features an easy access battery
compartment. Add this tuner to your stomp box setup
and stay in the pedal world
Enjoy

Connection 1- Continuous Tuning

Connection 2 - MUTE Silent Tuning

Connection 3- Continuous Tuning with
another stomp box

Connection 4 - MUTE Silent Tuning
with another stomp box.

Descriptions

Note Indicator LEDs -These LEDs show the note being tuned. The note
indicated above the LED (see point 2) is actual note being tuned.
Notes - This row of notes will light up when the unit is turned on. The LED
under the note being tuned will light up.
Flat Indicator LED - this flashing LED will light if the note being played is
flat. The more “flat” the note is, the faster the LED will flash.
In Tune LED - when the note being played is “in tune” this LED will light.
Sharp Indicator LED - this flashing LED will light if the note being played is
sharp. The more “sharp” the note is, the faster the LED will flash.
Calibration Button - this button is used to calibrate the X-Tune to match the
pitch of any instrument or audio source (like an old piano or tape player). For
details on this function - see section titled “X-Tune Calibration.”
DC 9V Input - To use external power (not provided) use only a 9-Volt DC
adapter
Input - Using a standard guitar cable with a 1/4” jack, plug your guitar into
this jack.
OUT TO AMP - Continuous Output Jack - If you would like to be able to hear
the guitar note while tuning connect a standard guitar cable with a 1/4” jack
connect to your next effect or directly into your amplifier.
OUT TO AMP - Mute Silent Tuning Jack - If you would like to be able to
mute the output of your guitar going to your amplifier or next stomp box so
that you can tune in silence - connect a standard guitar cable with a 1/4” jack
connect to your next effect or directly into your amplifier.

X-Tune Calibration
To match the pitch of any instrument or audio source (like an old piano or tape
player) press the “Calibration” button while simultaneously playing the note on the
instrument. (Note: you might have to first tune one string on the guitar or bass by
ear to match the actual note if the piano is out of standard tuning or if the tape
player you are playing along with runs slower or faster than normal). Once you
have one note on the guitar tuned to the source - simply play that note on the guitar -
while the note is “ringing” press the Calibration button. The tuning pitch of the
tuner will automatically be shifted to match the pitch of the audio source. Release
the button and tune the remaining strings as normal with the tuner The tuner at this
point has automatically adjusted the tuning range to match that pitch. To reset the
tuner to standard 440Hz pitch turn off the tuner and then back on again with the
footswitch (see controls - point 11).

Flat Indicator LED - this flashing LED will light if the note being played is
flat. The more “flat” the note is, the faster the LED will flash. Tune the string
up until the LED stops flashing and the “IN TUNE” LED lights.
IN TUNE LED - when the note being played is “in tune” this LED will light.
Sharp Indicator LED - this flashing LED will light if the note being played is
sharp. The more “sharp” the note is, the faster the LED will flash. Tune the
string down until the LED stops flashing and the “IN TUNE” LED lights.
These letters indicate the notes in the standard tuning range for guitar. These
notes will “light-up” when the X-Tune is turned on...this is ideal for tuning on
dark or dimly lit stages.
These LEDs will light depending on the note being played. These LEDs are
indicator lights for the notes A, B, C, D, E, F, and G
These LEDs will light depending on the note being played. These LEDs are
indicator lights for Sharp notes or flat notes - A# or Bflat, C# or Dflat, D# or
Eflat, F# or Gflat, or G#
These dots are the note indicators for A# or Bflat, C# or Dflat, D# or Eflat,
F# or Gflat, or G#.

Tuning Instuctions
Step 1 - plug the guitar/bass into the tuner - see “connections” section.
Step 2 - play a note on your guitar. In the example on the following page we are
tuning the low E string on a guitar or bass. Pluck your E string, and if needed,
adjust your tuning machine on your instrument until the LED under note “E” is lit
(indicated as 1 in the preceding diagram).
Step 3 - if your note is flat - the “FLAT” LED will light and flash. The speed of the
flash will show you by “how much” your string is flat. If the Flat LED is flashing
rapidly, tune your string up. During this process the LED will begin flashing
slower. (Indicated as point 2 in the preceding diagram).
Step 4 - if your note is sharp - the “SHARP” LED will light and flash. The speed of
the flash will show you by “how much” your string is sharp. If the Sharp LED is
flashing rapidly, tune your string down. During this process the LED will begin
flashing slower. (Indicated as point 3 in the preceding diagram).
Step 5 - Continue with step 3 or step 4 until the flat or sharp LED stops flashing and
the blue “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.

Hints and Tips:
The X-Tune 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 MUTE Silent Output Jack is ideal for tuning in live situations. This will allow
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.
When using the X-Tune with the Continuous Output Jack, make sure you turn off
your tuner once you are done tuning. Leaving the tuner on will run down the
battery.
