The pitchblack Pro is a rackmount tuner that's easy to see even from a distance. The crisp lights in the newly-developed tuning meter provide a revolutionary visual effect. The powerfully illuminated color LEDs provide unparalleled brightness, so discrepancies or changes in pitch are instantly obvious. There are three available display modes available for the large meter, Regular, Strobe and Half Strobe. Also, Korg's revolutionary Cable Checker function is built in, helping to minimize last minute problems. There is also a buffered output to minimize any change or additional noise in the audio input signal.
