From Manufacturer
Designed as the flagship model of Korg's successful tuning pedal series, the Pitchblack X Pedal Tuner is an advanced and flexible tuning stompbox with a wide tuning range, high detection accuracy within ±0.1 cents, and a rugged diecast aluminum body that can survive years of intense gigging. The adjustable, bright LED display can be easily viewed from any angle, under any lighting conditions, and comes with four display modes: Meter, Full Strobe, Half Strobe, and Mirror.
Tuning can be calibrated manually in 1 Hz steps and power options are versatile, allowing you to power your pedal via a 9V battery or an optional AC adapter, and even daisy-chain power output to another pedal in your setup. When tuning is done and it comes time to play, two bypass options are offered: a true bypass circuit, which passes your signal directly to the bypass output without any coloring (perfect for use with large pedalboard setups) and a new high-impedance Ultra Buffer amp circuit, which helps maintain signal strength over very long cable runs.
- Meter Mode: Similar to a needle meter, this mode allows you to tune by lining up the green LED with the center, with lights to the right being sharp and lights to the left being flat.
- Full Strobe Mode: Tune your instrument by making the LED meters stop streaming. The LED meters will stream from left to right if your instrument is sharp and from right to left if it is flat.
- Half Strobe Mode: Tune your instrument by making the LED meters stop streaming and only the green LED in the center is lit. When pitch is correct, only the center LED will be lit.
- Mirror Mode: Tuning is performed by making the two LEDs on the left and right sides of the center LED meet in the middle and both tuning guide LEDs are lit. The pitch lit LEDs will spread farther apart the more your instrument is out of tune. The left tuning guide will light if your instrument is flat, and the right tuning guide will light if your instrument is sharp.
