Owners playing in drop A and lower report the Korg Pitchblack effectively picks up lower tunings without issues, particularly when the instrument's volume is sufficiently high.

It's suggested to use the 12th fret harmonic for tuning, especially when dealing with lower tunings on bass guitars, as it provides a more reliable frequency for tuners to track.

It's recommended to solo the neck pickup and turn down the tone/treble to eliminate harmonics that might confuse the tuner, aiding in more accurate low-string tuning.

The Boss TU-2 and TU-3 tuners are frequently recommended over the Korg Pitchblack for their reliability in picking up low-tuned strings, with many users reporting no issues in lower tunings.
