Chromatic versus
polyphonic tuning
Setting instrument type
(guitar or bass)
A very simple guitar tuner will only allow you to
tune open strings, one string at a time – e.g. E, A,
d, g, b, and e’ for the standard tuning of a guitar.
By default, PolyTune Clip is set up for tuning guitars. To tune a bass, press and hold the Display
Mode Button for more than 5 seconds. The secondary display will display “B”.
PolyTune Clip is a chromatic tuner – meaning it
will detect and allow you to tune all twelve notes
of the scale.
But that’s not all. Other than a traditional tuner, PolyTune Clip allows you to play all your instrument’s string simultaneously when tuning.
PolyTune Clip will detect which strings need to
be tuned and indicate those strings in its display.
This allows you to tune your instrument much
To return to Guitar Tuning Mode, press and hold
the Display Mode Button for more than three
seconds again. The Secondary Display will display “G”.
Battery life
Depending on the quality of the button cell lithium battery you are using, you can expect a battery life of approximately 18 hours. This means
that after inserting a fresh battery, you should
be able to tune your instrument for three minutes
every day for a full year.
PolyTune Clip turns off automatically after 3 minutes, but to increase battery life, you might want
to turn it off manually after tuning.
The selected instrument type will be stored and
preserved even when you change the battery.
Finally, you may have tuned one or all strings on
your instrument differently from standard tuning,
or you may be using a capo to change the playable length of the strings.
In all these situation, PolyTune Clip has you co­

Switching Display Modes
Needle Mode
Strobe Mode
If you press the Display Mode Button once, the
currently selected Display Mode will be shown.
Pressing the Display Mode Button repeatedly will
cycle between the two display modes described
in this section.
In Needle Mode, when you tune a single string,
pitch is indicated by a column of five LEDs in the
main display, and the name of the target note is
displayed in the secondary display.
In Strobe Mode, the difference between the
correct (target) frequency and the actual detected frequency is displayed by two indicators
If the string you are tuning is too low, LEDs to
the left of the center column will light up. If the
string is too high, LEDs to the right of the center
column will light up.
1.Red LEDs to the left (pitch too low) or to the
right (pitch to high) of the center LED column
–– Needle Mode is indicated by the center LED
column and row lighting up.
–– Strobe Mode is indicated by the middle row
of LEDs lighting up.
The selected Display Mode will be stored and
preserved even when you change the battery.
Tune the string until the middle column and the
middle row of green LEDs lights up. This means
you are “on target”.
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 a stop and only the middle column
of green LED lights up.

Polyphonic tuning
Polyphonic tuning and Bass Mode
Alternate tunings and capos
As you know by now, PolyTune Clip is a polyphonic tuner. You can strum your instrument,
and PolyTune Clip will analyze and display the
tuning of all strings. So how do you activate polyphonic tuning mode?
Please note that polyphonic tuning is only available for guitar. If you select Bass Needle Mode
or Bass Strobe Mode, polyphonic tuning is disabled.
There’s more to life than E A D G B E’! You may
have tuned all strings of your instruments down,
or you may be using a capo. In that case, tell
PolyTune Clip about your instrument’s tuning by
pressing the Tuning mode button.
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 (flat) or above (sharp) the middle row.
Tune your guitar and strum again. Your instrument is in tune when each string is represented
by two green LEDs in the middle row.
If you play guitar and you don’t want to use polyphonic tuning at all, you can also change the
instrument type to Bass by pressing and holding the Display Mode Button for more than 5
seconds – see “Setting instrument type (guitar
or bass)” (page 7). You will still be able to
tune your guitar chromatically, but strumming
multiple strings will not trigger polyphonic tuning anymore.
If you press the Tune Mode Button once, the current tuning will be displayed (“-- E --” for standard tuning). Pressing the Tune Mode Button repeatedly will cycle through the following tunings:
--- E --Eb
Gb 2
Ab 4
Bb 6

even when you change the battery.

How to use PolyTune Clip
Changing the reference pitch
In most cases, you may want to tune your what
is considered standard pitch, where the A above
the middle C has a frequency of 440 Hz.
However, you and your band may prefer a different pitch, or you may have to tune to an acoustic
instrument that cannot easily be retuned. In that
case, you need to change the reference pitch.
–– To change the reference pitch, press the Display Mode Button and the Tuning Mode Button simultaneously.
The display will show the current reference
pitch (e.g. “440” for 440 Hz).
–– To increase the reference pitch in 1 Hz steps,
press the Tuning Mode Button.
–– To decrease reference pitch in 1 Hz steps,
press the Display Mode Button.
–– To accept the currently displayed reference
pitch and return to normal operation, do not
press either button for two seconds. The set
reference pitch will blink three times.
The selected reference pitch will be stored and
preserved even when you change the battery.
