The Korg PB-02 pitchblack+ is a high-end pro-quality chromatic pedal tuner boasting ultra-high tuning accuracy within a range of +/-0.1 cents. Housed in a sleek black aluminum die cast body, the Korg pitchblack+ packs a versatile range of tuning modes such as chromatic, standard (guitar/bass), open D, open E, open G, open A, and DADGAD. The Korg pitchblack+ also creates up to 5 custom tuning programs of your own with any temperament you specify. This is ideal for accommodating special tunings such as ethnic instruments and stretched tuning. The Korg pitchblack+ tpedal tuner also supports tuning for 7-string guitars and 6-string basses. In addition, you can also use the flat tuning mode to tune your instrument as many as seven semitones below standard pitch. With a broad tuning range of E0 (20.60 Hz) to C8 (4186 Hz) and calibration that's adjustable in a range of 436”445 Hz, you'll be able to tune with an unprecedented degree of accuracy. The Korg pitchblack+ offers a new level of high-precision tuning demanded by professional guitar and bass players for the recording studio or in live performance.

Large surface-illuminated LED display ensures easy tuning
The Korg pitchblack+ tuner features a large 13-segment LED meter. In conjunction with the tuning guides located below the meter that indicates whether your instrument is sharp or flat, the smooth-moving LED's provide highly visible confirmation for accurate tuning at any viewing angle. The note name, tuning mode, and calibration are shown by large, highly-readable displays in green and red, and the tuner on/off status is shown by a red LED, ensuring that you'll see everything you need even if you're on a dimly-lit stage. You can choose between two types of display modes: Single mode or Double mode. In Single mode, you can choose between Meter mode, Full Strobe mode, Half Strobe mode, or Mirror mode. In Double mode, you can choose from two newly developed modes; "Focus mode 1" and "Focus mode 2" which offer even greater precision with excellent visibility.

Dual input jacks allow two instruments to be connected. True Bypass ensures that the input signal is unaffected.

As a professional pedal tuner, the Korg pitchblack+ provides A and B input jacks to which you can connect 2 different guitars or basses, and individually specify a separate calibration, tuning mode, flat tuning, and display mode for each guitar/bass (input). If only a single instrument is connected to the pitchblack+ tuner, you can specify 2 different tuning settings and switch between them by pressing the "INPUT SELECT" foot switch. This supports situations such as when you're playing more than one guitar/bass in a live situation, or sophisticated musical needs such as using different tunings with a single guitar for multiple songs. The sound is muted when tuning is active, and when the Korg pitchblack+ tuner is off, the True Bypass feature ensures that the input signal from your instrument is not colored in any way whatsoever. With functionality such as this, the Korg pitchblack+ tuner can provide high-precision tuning capability while being integrated into your guitar or bass pedal board and amp setup.

Fits into your pedal board, and DC output powers other pedals
The Korg pitchblack+ tuner works great with your current pedal board system. It provides a DC OUT jack that can supply power to other effect pedals when the optional AC adaptor is used. By connecting the included DC cable, you can supply up to 200 mA of power to multiple effect pedals that require a 9V supply, simplifying the power connections in your effect board.

Korg PB-02 pitchblack

By Carltonator

from Seattle, WA

Ah pitchblack, how do I love thee? Let me count the ways: 1) Nice big bright intuitive display. 2) Sensitive, accurate, reproducible electronics. 3) True bypass, no click. 4) Two inputs. Way better than two 1/2 pound tuners. 5) Full 88 key range. Tune anything alive! 6) Includes half steps. Sweet. 7) Useful for finding any note anywhere on your fretboard. Great educational tool. 8) Have even used it to reverse engineer score, since it displays every note played really fast. 9) I think it looks good. Don't need no chrome on the floor, any mo'. 10) Just buy one. Your life will be transformed.

Extremely accurate and fast

By gman

from orange ca

I got this tuner for adjusting my intonation because it has a strobe and is very accurate. There are so many display modes that make it easy to read .This tunner reacts so quickly and precise that I can tune once and not have to go back and balance string to string harmonics. I am kind of picky about being in perfect tune so this really saves time and I am happy with the end results.

Great tuner... when it works

By Evan

from Chicago, IL

I bought this tuner to have the pedal for easy tuning during gigs and for the dual input jacks. It's very accurate and easy to use, and it's great that it shuts off the output while you're tuning. The problem is, it's very unreliable. The first one I got died on me after only 2 uses. Since the local store where I got it would only give me an even exchange for a new one, I went with the same tuner despite the initial experience. It's worked well for the past 2 months, but just died again at practice yesterday.
