Korg is already well established in the tuning world - with its rack tuners adorning many pro rigs - but its newest tuner, the Pitchblack, is designed for pedalboards.
The Korg Pitchblack Chromatic Tuner is a sturdily-built aluminium stompbox equipped with a large 7-segment display to show the note, and a line of LEDs displaying how far the note is to the correct pitch, accurate to +/- 1cent. The LED display can be configured to run in a number of display modes which Korg calls meter, strobe, half strobe and mirror.
The Pitchblack is true bypass, and like the famous Boss TU-2 Tuner it features a 9volt DC output so you can power other stompboxes from your tuner. Its tuning range of 20Hz–4kHz means the Pitchblack is equally well suited to bass as to guitar, and the more avant garde players among you can calibrate concert A from 436-446Hz.
