The Korg PB-XS is a compact pedal tuner from Korg, sold as the Pitchblack X Series Mini Tuner. It carries the Pitchblack tuning format into a small enclosure measuring 70 x 80 x 47mm, with a list price of $92 as of June 20251. It sits in the mini tuner field alongside pedals like the Korg Pitchblack X mini, the TC Electronic Polytune 3 Mini and the Peterson StroboStomp Mini, and belongs to the wider family of tuner pedals.
Controls
The pedal keeps its control set simple, which is typical of a dedicated stompbox tuner:
- Bypass: switchable between buffered and true bypass1
- Calibration: adjusts the reference pitch1
- Display: brightness control1
Guitar Pedal X summarized the controls as "Bypass : Buffered / True, Calibration, Display : Bright"1.
How it compares
Writing in a 2025 buying guide to mini and micro tuner pedals, Guitar Pedal X made legibility the PB-XS's standout point: "it has the largest surface area for its format - and those provides the overall best legibility"1. The same review described it as a full size experience in a shortened format, which matters on a dark stage where a small display can be hard to read at a glance.
For players comparing options, the PB-XS is the shortened-format take on Korg's Pitchblack line, which also includes the full-size Korg Pitchblack X, the Korg Pitchblack XS and the earlier Korg Pitchblack Advance1.
