Giving you the ability to customize your tuning with its four meter display modes, the black Pitchblack Custom Pedal Tuner from Korg offers a +/-0.1 cent detection range for accurate tuning, for both electric guitars and basses. Thanks to its high-visibility screen, and durable aluminum die-cast construction, Korg's tuner is a valuable addition to your pedalboard.

The tuner indicates note name and tuning change with bright LED movement displayed on a vertical 3D visual meter, making pitch name and difference easily identifiable. With a choice of four display modes, Regular A, Strobe, Half Strobe, and Regular B (in which the meter rises by being stacked from bottom to top toward a reference line), you can customize your tuning process. Also, a broader pitch range is provided for the lower end, which can often be difficult to tune on standard tuners.

The Pitchblack's true bypass circuitry leaves the input signal unchanged when the tuner is off, delivering a transparent sound; and, since the input sound is muted when the tuner is on, it is useful in live performance situations. Also, its parallel DC output can deliver clean power to other effects pedals when using an additional power adapter (available separately).

Battery life is approximately 15 hours when using zinc-carbon batteries, and approximately 30 hours when using alkaline batteries.
