Pitchblack X: Korg's Next-Generation Pedal Tuner
With the Pitchblack X series, Korg aimed to set a modern standard for pedal tuners: immediate readability, reliable detection, and tuning precision designed for demanding musicians. The Pitchblack PB-XS fits this "pedalboard tour" logic: reduced footprint, direct foot operation, and sturdy construction to withstand transport, soundchecks, and stage changes.
Who is it for, which styles, and in what contexts?
The Korg Pitchblack PB-XS is intended for any guitarist who wants quick and reliable tuning without compromising visibility. It suits both beginners (simple and reassuring reading) and advanced or professional guitarists who need reproducible precision from one gig to another.
Rock, pop, blues, metal, funk, worship, indie, ambient: whatever the style, a reliable tuner is the foundation of a clean sound. In live settings, it becomes a reflex between songs. In studio, its Strobe mode helps lock intonation, open chords, and layering takes. On a pedalboard, its buffer (activatable or not) is a real advantage for managing losses related to cable lengths and extended effect chains.
