Connections

Turn off the power of all devices before you make any connections to avoid damaging your equipment.
The INPUT and BYPASS jacks are mono. Stereo (TRS) cables will not work.

INPUT jack
Connect a cable from your instrument to the INPUT jack of the tuner. When you do this, the calibration setting will blink for several seconds in the note name display.
Connecting a cable to the INPUT jack will turn the power on, but the tuner will not be in tuner mode. Press the TUNER ON/OFF switch to engage tuner mode.

• When a cable is plugged into the INPUT jack, the turner is turned on and starts consuming battery power. To conserve battery life, disconnect the cable from the INPUT jack when not in use.

BYPASS jack

• Connect a cable from the BYPASS jack to your other effect pedals or amp. When the tuner is switched on, the signal from the INPUT jack will be muted for silent tuning.
• The Pitchblack Custom was designed with a True Bypass circuit. When the tuner is not active, your tone will not be affected by any of its circuitry.

DC 9 V IN jack

• If you use an optional AC adapter for power, ensure that it is 9 volt ( ) and at least 600 mA. Using an AC adapter other than what Korg recommends may cause a malfunction or damage.
• When a plug is inserted into the DC 9 V IN jack, the battery cannot be used.

DC 9 V OUT jack

• When using an optional AC adapter, you can supply power to one or more effect pedals with an optional DC cascade cable.
• When using an optional DC cascade cable, make sure that the total amount of current consumption for the connected pedals does not exceed 200 mA. Furthermore, pay attention to the required polarity of the effect pedals when connected.
• Do not connect the AC adapter to the DC 9V OUT jack. Doing so will cause a malfunction or damage.
• If the Pitchblack Custom is activated using a battery, you cannot supply power from the DC 9V OUT jack.

Tuning

Tuning procedure

1. Press the TUNER ON/OFF switch to activate the tuner.
   The Tuning LED meter will light. Because the Pitchblack Custom has a True Bypass circuit, you can only tune “silently”, meaning you will not hear your audio signal through an amp etc.
   The TUNER ON/OFF switch only functions if an instrument is connected to the INPUT jack.
   If no audio signal is input within 4 hours, the tuner will turn off automatically. In addition, there will be no output from the BYPASS jack. If this occurs, press the TUNER
   ON/OFF switch again to activate the tuner in order to use your instrument.

2. If desired, adjust the calibration and/or select the display mode. The Pitchblack Custom comes from the factory with the calibration set to A=440 and the tuning mode set to Meter (see “Adjusting the calibration,” & “Choosing a display mode”).

3. Play a single note on your instrument and tune it so that the desired note appears in the note name display.
   The note name closest to the entered note appears in the note name display.

4. Tune your instrument using the tuning LED meter.
   The method for indicating whether your instrument is in tune, sharp or flat depends on which display mode you choose. (see “Choosing a display mode”)

5. After you finish tuning your instrument, press the TUNER ON/OFF switch to turn the tuner off.
   The tuning LED meter turns off. Now your signal will be heard through your amp.

Adjusting the calibration
The Pitchblack Custom comes from the factory with the calibration set to A=440 Hz. If an adjustment is necessary, you can do so within a range of 436–445 Hz.

1. Press the CALIB button.
   The current calibration setting will blink for several seconds in the note name display (Light → Blink).

2. While the current calibration setting is shown in the note name display, press the CALIB button again to adjust the setting.
   Each time you press the CALIB button you will cycle through the following settings.
   0: 440 Hz, 1: 441 Hz, 2: 442 Hz, 3: 443 Hz, 4: 444 Hz, 5: 445 Hz, 6: 436 Hz,
   7: 437 Hz, 8: 438 Hz, 9: 439 Hz

3. After you have selected your desired calibration setting, wait approximately two seconds without pressing any buttons.
   The new setting will blink three times in the note name display indicating the calibration has been set. The Pitchblack Custom will automatically return to tuner mode.
   The calibration setting will be remembered even if the power is turned off. However, this setting will be reset to the factory default (440 Hz) if the battery is removed or if the adapter is unplugged. In addition, this setting will be reset to the factory default if an adapter not connected to an AC outlet is plugged into the tuner, even if the battery is installed.

Choosing a display mode
The Pitchblack Custom allows you to choose one of four display mode settings. The
factory setting is Regular A mode.

1. Press the DISPLAY button.
   The current setting will blink for several seconds in the note name display (Light → Blink).

2. When the setting is shown in the note name display, press the DISPLAY button again to set the display mode.

• 1: Regular A
  Tune your instrument until the green LED in the LED meter is lit. The blue LEDs at the top will light up if the pitch is high, and the blue LEDs at the bottom will light up if the pitch is low.

• Strobe
  Tune your instrument until the LEDs stop running. Since the strobe meter has higher precision, it allows you to tune with greater accuracy. The LEDs light up, running from bottom to top if the pitch is high and from top to bottom if the pitch is low.

• Half-strobe
  Tune your instrument until the LEDs stop running and only the green LED is lit. The blue LEDs at the top will strobe if the pitch is high, and the blue LEDs at the bottom will strobe if the pitch is low. When the pitch is in tune, only the green LED is lit.

• Regular B
  Tune your instrument until all of the lower blue LEDs and the green LED are lit. If the pitch is high, the upper blue LEDs will also light up.

After you’ve chosen the display mode you would like to use, wait approximately two seconds without pressing any buttons. The note name display will blink two times, the display mode will be set, and the Pitchblack Custom will automatically return to tuner mode.
The display mode setting will be remembered even if the power is turned off. However, this setting will be reset to the factory default (Regular A) if the battery is removed or if the adapter is unplugged. In addition, this setting will be reset to the factory default if an adapter not connected to an AC outlet is plugged into the tuner, even if the battery is installed.
