High precision and advanced functionality and sleek style make this new guitar/bass pedal tuner from Korg our most advanced yet. The Pitchblack is the same size as a compact effect unit and features a tough aluminum die cast body that will endure hard use on the road or in the studio. While small in size, it boasts a large; easy to read LED meter with a light-emitting surface for excellent visibility in any setting from daylight to stage light to no light as well as an extremely smooth eleven-segment LED meter that allows accurate visual tuning from any angle. With a red LED that indicates the tuner's on/off status, a large note name display, and a tuning guide that indicates whether your instrument is sharp or flat, you'll always be able to tune quickly and accurately in any situation. The Pitchblack provides a tuning range of E0 (20.60 Hz) to C8 (4,186 Hz), and adjustable calibration between 436--445 Hz.
