2. Introduction
As the world’s first polyphonic tuner, the original POLYTUNE took the hearts
of guitarists by storm. Features such as the MonoPolytechnology (which
automaticallydetects whether you want to tune asinglestring or all strings)
made tuning abass or guitar faster and easier than ever before.
So how do you make the best-selling polyphonic tuner even better? You take
it to the next level by: providing multipletuning modes, including polyphonic,
chromatic, strobe and avariety of altered tunings; adding an onboard BONAFIDE
BUFFERto preserve your tone over long cableruns and pedal board signal paths;
and upgrading the LEDdisplay for even higher tuning accuracy.
Enter POLYTUNE 3.
2.1 Unpacking
Your TCELECTRONICeffect pedal box shouldcontain the following items:
•• Your TCELECTRONICeect pedal
•• 1TCELECTRONICsticker
•• 1Quick Start Guide for quick information about the pedal’s controls
Inspect all items for signs of transit damage. Inthe unlikelyevent of transit
damage, inform the carrier and supplier.
Ifdamage has occurred, keep all packaging, as it can be used as evidence of
excessive handling force.
2.2 Setting up
Connect a9V power supplywith the following symbol to the DC input socket of
your TCELECTRONICeffect pedal.
This product does not come with apower supply. We recommend using
TCELECTRONIC’s PowerPlug 9(soldseparately).
•• You can also power POLYTUNE 3 using astandard 9V battery (not included),
but if you intend to power additional pedalsusing the power out jack, you
need to use apower supply.
•• Plug the power supplyinto apower outlet.
•• Connect your instrument to the in jack on the right side of the pedal using a
¼"jack cable.
•• Connect the out jack on the left side of the pedal to your amplier using a
¼"jack cable.
•• Ifyou have another 9V guitar pedal that you want to power, connect it to the
power out socket on the rear of the pedal.
2.3 Get ready for a new tuning experience!
Tuning your instrument with POLYTUNE 3 is fast and intuitive. Ifyou don’t feel
like reading the manual,just strum your instrument and watch the display.
We think you’ll like what you see.
Ifyou want to learn more – read on!
2.4 True Bypass
Here at TCELECTRONIC, we have asimplephilosophy: When you are using one of
our products, you shouldhear something great – and if you don’t, you shouldn’t
hear it at all.This is why this pedal sports True Bypass. When it is bypassed, it is
reallyo and has zero inuence on your tone, resulting in optimum clarity and
zero loss of high end.
POLYTUNE 3 lets you switch between True Bypass and Buered Bypass modes,
the latter giving you an “always on” option that keeps the tuner in full operation
– even when your signal is not muted. Tuning made simpleand more ecient
than ever.
Sometimes, it is advisableto switch an eect pedal from True Bypass to Buered
Bypass mode. For more information, see “6.2 Switching between True Bypass to
Buered Bypass”.
2.5 Brighter than a thousand suns
When you need to tune, you need to tune. And the last thing you want to worry
about at that moment is adisplay that is either too bright for the club stage or
unusablein the bright sun of alate afternoon gig. The display on POLYTUNE 3 is
primed with some of the brightest LEDs you have ever laid your eyes on. And the
ambient light sensor makes sure you get just the right amount of brightness. It’s
the best of/for both worlds!
2.6 Strobe tuning
TChas received many requests from the guitar community for astrobe tuner, so
we added astrobe mode, which is both lightning fast and ultra precise. And with
apitch detection accuracy of ±0.1 Cent, (that’s 1/1000 of asemitone!)this is the
right tool for ne-tuning your precious instrument – wherever you may be.
2.7 Total recall
POLYTUNE 3 stores your preferences. From pitch reference to selected tuning
mode, it hangs on to this information even after it is powered down – making
sure you onlyhave to set these parameters once. And just to be safe, it will
display the current settings when you plug in your instrument.
One less thing to worry about!
Of course, POLYTUNE 3 still has all the features from the original POLYTUNE that
users know and love.
•• POLYTUNE®:Tune all strings simultaneously
•• For guitars and basses
•• Supports Drop-D and capo tuning modes
•• True bypass with silent tuning
•• Buered bypass to compensate for long cableruns
•• DC output for powering other pedals
POLYTUNE 3 will allow you to tune your instrument faster and easier than ever
before, so you can go back to doing the one thing we know you care about:
playing your music.
Enjoy!
3. Operation – Inputs, Outputs
and Controls

of the pedal.
The audio input of this pedal is astandard ¼"jack (mono/TS).
When you connect your instrument to the audio input, the following
information will be displayed:
•• Standard (“STD”)or Drop Dtuning mode
•• the currentlyselected display mode (Needle/Strobe, Guitar /Bass)
•• the currentlyselected tuning mode
•• the reference pitch.
For best results, place POLYTUNE 3 in your signal chain before your drive,
distortion and vibrato pedals. Adistorted or modulated signal is
harder to analyze.
Ifthe pedal runs on battery power, we recommend removing your
instrument from the audio input to preserve battery power when you
don’t play.
(9) AUDIO OUTPUT Connect the OUT jack of POLYTUNE 3 to the input jack of the
next device in the signal chain.
The audio output of this pedal is astandard ¼" jack (mono/TS).

for tuning.
•• POLYTUNE 3 features atrue bypass circuit that leaves your beloved tone
unaltered when the tuner is bypassed.
4. Operation – Tuning with
POLYTUNE 3
4.1 Chromatic vs. polyphonic tuning
Avery simpleguitar tuner will onlyallow you to tune open strings, one string at a
time – e.g., E-A-D-G-B-E for the standard tuning of aguitar.
POLYTUNE 3 is achromatic tuner – meaning it will detect and allow you to tune
all twelve notes of the scale.
But that’s not all.Other than atraditional tuner, POLYTUNE 3 allows you to play
all of your instrument’s string simultaneously when tuning. POLYTUNE 3 will
detect which strings need to be tuned and indicate those strings in its display.
This allows you to tune your instrument much faster.
Finally, you may have tuned one or all strings on your instrument dierentlyfrom
standard tuning, or you may be using acapo to change the playablelength
of the strings.
Inall of these situations, POLYTUNE 3 has you covered.
4.2 Display modes
Ifyou press the display mode button on the rear of POLYTUNE 3 once, the
currentlyselected display mode will be shown. Pressing the display mode button
repeatedlywill cyclethrough these modes:
•• Guitar / Needle mode (indicated by a“G” and the center LEDcolumn
lighting up).
•• Guitar / Strobe mode (indicated by a“G” and the middlerow of LEDs
lighting up).
•• Bass / Needle mode (indicated by a“B” and the center LEDcolumn
lighting up).
•• Bass / Strobe mode (indicated by a“B” and the middlerow of LEDs
lighting up).
4.3 Needle mode
InNeedle mode,when you tune asinglestring, pitch is indicated by acolumn
of ve LEDs in the upper part of the display, and the name of the target note is
displayed at the bottom of the display.
Ifthe string you are tuning is too low, LEDs to the left of the center column will
light up. Ifthe string is too high, LEDs to the right of the center column will
light up.
Tune the string until the middlecolumn and the middlerow of green LEDs lights
up. This means you are “on target”.
Needlemode – Astring in tune
4.4 Strobe mode
InStrobe mode, the dierence between the correct (target) frequency and the
actual detected frequency is displayed by two indicators simultaneously:
1. Red LEDs to the left (pitch too low) or to the right (pitch to high) of the center
LEDcolumn
2. Rotating segments in the display. The closer the detected frequency is to the
target frequency, the slower the rotation.
Tune the string until the rotating pattern has come to astop and onlythe middle
column of green LEDlights up.
4.5 Polyphonic tuning
As you know by now, POLYTUNE 3 is apolyphonic tuner. You can strum your
instrument, and POLYTUNE 3 will analyze and display the tuning of all strings.
So how do you activate polyphonic tuning mode?
You don’t – it just works. Strum, tune, rock on!
Strum your guitar. Strings that are in tune will be represented by two green LEDs. Strings that need
tuning are represented by two red LEDs below (at) or above (sharp) the middlerow.
Tune your guitar and strum again. Your instrument is in tune when all strings are represented
by two green LEDs in the middlerow.
Of course, onlythe strings that are actuallypresent and played will be shown in
the display. So if you tune afour string bass, onlyfour LEDcolumns will light up.
4.6 Drop D tuning
“Drop D” is apopular tuning (also known as D-A-D-G-B-E)in which the lowest
string of aguitar is tuned down (“dropped”)from E to D.
Ifyou want to tune an instrument set to “Drop D”,follow these steps:
1. Press and holdthe POLYTUNE 3 footswitch for about three seconds.
2. The word “DROP” will be displayed briey, and the default“ready for tuning”
indicator at the bottom of the display will change from asmall
square to a“d”.
3.Ifyou want to switch POLYTUNE 3 back to standard tuning, press and hold
the footswitch for three seconds again.
4.“STD” will be displayed briey, and the “ready for tuning” indicator will go
back to asmall square.
4.7 Alternate tunings and capos
There’s more to life than standard E-A-D-G-B-E tuning! You may have tuned
all strings of your instruments down, or you may be using acapo. Inthat case,
tell POLYTUNE 3 about your instrument’s tuning by pressing the TUNING MODE
button.
Ifyou press the TUNING MODE button once, the current tuning will be displayed
(“-- E --” for Standard Tuning). Pressing the tune button repeatedlywill cycle
through the following tunings:
Display Mode
--- E --- Standard Tuning
EbAll strings tuned down 1semitone
DAll strings tuned down 2semitones
Db All strings tuned down 3 semitones
CAll strings tuned down 4 semitones
BAll strings tuned down 5 semitones
F 1Capoat rst fret
Gb 2 Capo at second fret
G3 Capo at third fret
Ab 4 Capo at fourth fret
A5 Capo at 
fth fret
Bb 6 Capo at sixth fret
B7 Capo at seventh fret
Ifyou do not touch the TUNING MODE button for two seconds, the display will
blink twice, and the selected tuning will be used.
The selected tuning mode is stored and will be recalled when you power on
POLYTUNE 3 again.
4.8 Changing the reference pitch
Inmost cases, you may want to tune to standard pitch, where the Aabove the
middleChas afrequency of 440Hz. However, you and your band may prefer a
dierent pitch, or you may have to tune to an acoustic instrument that cannot
easilybe retuned.
Inthat case, you need to change the reference pitch.
Tochange the reference pitch, follow these steps:
1. Press the DISPLAY MODE button and the TUNING MODE button (3)
simultaneously.
2. The display will show the current reference pitch (e.g., “440” for 440Hz).
3.Toincrease the reference pitch in 1Hzsteps, press the TUNING MODE button.
4.Todecrease reference pitch in 1Hzsteps, press the DISPLAY MODE button.
5.Toaccept the currentlydisplayed reference pitch and return to normal
operation, do not press either button for two seconds.
The selected reference pitch is stored and will be recalled when you power on
POLYTUNE 3 again.

5. Frequently Asked Questions (FAQ)
“I’m not hearing anything!”
When the tuner is active, the output will be muted for silent tuning.
“The pedal has power supply, but pressing the footswitch doesn’t
do anything!”
Tooperate POLYTUNE 3,you need to connect an instrument to the pedal’s audio
input jack.
“The display shows a red ‘#’ – what does this mean?”
This is the symbol of the Secret Brotherhood of the Tune-O-Calypse of Doom –
and it is telling you that you are not playing loud enough…
Just kidding. This symbol shows that your POLYTUNE 3 is not bypassed and
ready to display the pitches of your instrument’s strings. Please note that this
also means that POLYTUNE 3’s audio output is muted. Tounmute, press the
footswitch.
“How do I get the best (most accurate) results?”
We have found that you will achieve the most accurate tuning of electric guitars
in polyphonic mode by selecting the guitar’s neck pickup and using the thumb to
strum the strings.
6. Operation – Bypass Mode
6.1 True Bypass and Buered Bypass explained
True Bypass mode is ahard-wire bypass that gives absolutelyno coloration of
tone when the pedal is bypassed. This is the defaultmode for your eect pedal.
Using True Bypass on all pedalsis aperfect choice in setups with afew pedalsand
relativelyshort cables before and after the pedals.
If...
•• you use along cablebetween your guitar and the rst pedal or
•• if you use many pedalson your board or
•• if you use along cablefrom your board to the amp,
... then the best solution will most likelybe to set the rst and the last pedal in
the signal chain to Buered Bypass mode.
Can you hear the dierence between a pedal in True Bypass or Buered
Bypass mode?
Maybe, maybe not – many factors apply: active vs. passive pick-ups, single-coil
vs. humbucker, cablequality, amp impedance and more. We cannot give asingle
ultimate answer. Use your ears and nd the best solution for your setup!
6.2 Switching between True Bypass and
Buered Bypass
Toset the bypass mode, proceed as follows:
•• Disconnect the pedal and turn it on its back.
•• Unscrew the back plate of the pedal and look for the two small DIP-switches
in the upper left corner.
•• These two DIPswitches oer three modes:
Switch conguration Mode
Both switches set to the left True Bypass
Top switch set to the right
Lower switch set to the left
Buered Bypass
Both switches set to the right Buered Bypass Display Always On
•• Set the DIPswitch to the desired position.
•• Remount the back-plate.
