Korg PB-04 overview

  • 1Description

Providing polyphonic tuning with support for a variety of alternative guitar and bass tunings, the red Pitchblack Portable Guitar/Bass Polyphonic Tuner from Korg features a slim aluminum body that can be placed on the top of your amp or in your pedalboard. Its LED meter has 3 modes to select from: regular, strobe, and half strobe, and has precision up to +/- 0.1 cents when in strobe mode. It supports a number of alternate tunings as well, including flat up to 5 semitones, capo up to 6 semitones, and drop-d tunings.

The tuner has a built-in cable checker function and supports DC output (when being powered by an optional AC adapter) for powering other pedals on your pedalboard.

LED Display
The 150 mm wide display draws the player's attention, and the colorful high-brightness LEDs provide ample visibility. Whether it's placed by your feet, on top of your amp, or on a dimly-lit stage, the Pitchblack Portable delivers noticeable visibility in any situation
Polyphonic Tuning
This tuner features the same polyphonic tuning functionality as found on the Pitchblack Poly. Play all open strings at once, and the polyphonic meter (green/red) in the lower part of the unit will illuminate, showing you at a glance which strings require tuning. Just tune the strings that require tuning. (If all strings are perfectly in tune, you'll see a horizontal line of green LEDs.) With all open strings ringing out, turning the tuning peg of any string will cause the "String Seeker" function to automatically detect that string. The meter (white/blue) found on the upper part of the unit will instantly zoom-in to show the tuning status so you can accurately tune the required string
3 Meter Display Modes
  • Regular Meter Mode: As when using a needle-type meter tuner, tune the string so that the white LED in the center of the meter is lit. The illuminated LED will move to the right if the string is sharp, or toward the left if the string is flat
  • Strobe Meter Mode: Tune the string so that the LED meter illumination stops flowing. The illumination will flow from left to right if the string is sharp, or from right to left if the string is flat
  • Half Strobe Meter Mode: Tune the string so that the LED meter illumination stops flowing and only the center white LED is illuminated. The right side of the LED meter will strobe if the string is sharp; the left side if the string is flat. When the pitch is correct, only the center LED will be lit up
Works with Floating Tremolo Systems
Guitarists who use a "floating tremolo system" will have noticed that one out-of-tune string may affect the tuning of the other strings; so a single flat string may cause the other strings to sound sharp. With a traditional tuner, this may require tuning and retuning each string multiple times. The Pitchblack Poly makes it easy to identify and correct the one flat string, causing the other strings to sound their correct pitch
Automatic Detection of Guitar/Bass, Supports Flat, Capo, and Drop-D Tuning
Korg's proprietary functionality will automatically detect whether the input signal is a guitar or bass (4-, 5- and 6-string basses are supported). In addition to regular tuning, you can also choose alternative tunings such as flat, capo, or drop-D
Cable Checker
Korg's Cable Checker function is built into the Pitchblack Portable; simply connect the two ends of your monaural phone cable to the INPUT jack and the CABLE CHECK jack, and the display will tell you whether the cable is broken. This is a convenient way to avoid problems on stage or in the studio
Buffered and Mute Output
The Pitchblack Portable is designed with a buffered output to minimize any change or additional noise in the audio input signal. There's also a Mute function that lets you tune without producing sound from the OUTPUT jack
Sized for Your Pedalboard
The Pitchblack Portable is sized like a pedal effect unit, and will fit into most effect pedalboard systems. In addition, the Pitchblack Portable also provides a DC OUT jack that can be used to feed power to other effect pedals (when using the optional AC adapter). With a dedicated power supply circuit for the DC OUT, this jack is able to provide a stable and noiseless power supply (9V 200mA) that's equivalent to a dedicated effect pedal power supply. By connecting a commercially available DC cable, you can supply power to multiple effect pedals, allowing you to simplify the power connections in your pedalboard
Slim Horizontal Body
The slim horizontal body made out of extruded aluminum occupies little space, easily fitting into a gap in your effect pedalboard, or placed on top of your amp
String Seeker function
Tuning of +/-0.1 cents (when using strobe meter)
